    NASA space data supports citizens' observations: Meteor fireballs are increasing exponentially

    Dr. M.A. Rose
    Sott.net Sat, 09 Jan 2016 20:05 UTC

    SOTT.net last looked in detail at the frequency of meteor fireballs in 2013, using the data garnered by the American Meteor Society (AMS). SOTT.net pointed out the increasing frequency of fireballs1, and asked the question: "What does 2014 have in store?"

    Well, the results are in, and the answer is simple: comparing 2014 to 2013, the frequency of fireballs increased by 120%. Comparing 2015 to 2014, fireballs increased by 20%. That is a significant increase, and it should be generating a lot of attention. If it is, then it's being done very quietly behind closed doors.

    Since October 2013, the web site spaceweather.com has published daily data from NASA's All-Sky Fireball Network, which observes, and daily reports, fireball activity over the US.2

    I have collated both sets of data - from NASA and the AMS - to produce the following graphs, taking into account that each dataset relies on different definitions of 'meteor fireball'. Click on the graphs to view them at full size.

    Because we are using two datasets, there can be some incongruity for the 2013-2014 data. Nevertheless, the pattern is congruent: from 2010 onwards, the frequency of fireballs has been increasing each year in an exponential fashion. Such a change is significant and should be generating a lot of media attention and a lot of activity in near space observation.

    The most significant way to plot the data is via a 12-month rolling average, which smooths out 'noise' and demonstrates any significant changes that have occurred. From mid-2010, the average number of fireballs significantly increased, until late 2015 when the rolling average stabilised.

    Collating the data into a 6-month rolling average reveals the asymmetric distribution across the year. Fireballs are occurring at higher numbers in the latter part of the year. This difference in distribution significantly increased after 2013. That is, one part of space is becoming dense with dust and rocks, and Earth (and other planets in the inner solar system) are moving through this area of space every year.

    [see original article for more diagrams]

    Looking at NASA's data month by month, we see that the fireball frequency is most concentrated in the months August to December. However, the numbers for June and July are also increasing significantly, suggesting that the area of space from which asteroid and comet debris is reaching Earth (or, alternatively, into which the solar system is moving), is increasing in size:

    Where there is meteor smoke, there are asteroids

    NASA has also published data for near-Earth asteroid (NEA) discoveries since 1995.3 Their data shows a consistent increase in asteroid numbers from 1998-2013, and significant increases for 2014 and 2015, which shadows the big increases in fireballs observed over those two years.


    © Dr M.A. Rose - Increase in Near Earth Asteroids in last two decades

    Another remarkable change is the increase, since 2000, in the outer planets' new moons/satellites.4 Jupiter and Saturn appear to have effectively shielded the planets in the inner solar system by trapping the larger 'rocks' in their gravitational fields, in the process gaining new moons:


    © Dr. M.A. Rose - Increase in the number of satellites acquired by the outer planets of the solar system

    This might be related to the decline, since 2000, in new discoveries of large NEAs (rocks greater than 1km in diameter):


    © Dr. M.A. Rose


    To summarize, here's what we can deduce from these datasets:
    1. The number of fireballs being observed has slowly increased over the years 2000-2011. Thereafter, their numbers increased rapidly, and moreover, the very rapid increase came from a specific area of space. Most occurred during the period August to December. 2014 and 2015 saw major increases in fireball numbers
    2. NEA numbers have been observed since 1995. From 1998-2013 the number of new NEAs discovered has relentlessly increased, with major increases in 2014 and 2015. The pattern matches that of the recorded fireballs
    3. The number of discoveries of large NEAs peaked in 2000, then declined to 2010, and plateaued out thereafter
    4. Saturn and Jupiter began increasing their number of moons circa 2000/2001, and the numbers stabilized around 2010
    It would be interesting to plot the positions of the large outer planets relative to Earth over this time period, and determine whether the decrease in large NEAs in 2000 is connected to the increase of moons around the outer planets - that is, whether the outer planets, when in the right part of space, capture the larger rocks/asteroids.


    More intense meteor showers and more sporadics

    We have a limited database from NASA, but the following meteor showers revealed significantly increased fireball numbers for 2015 as compared with 2014:
    • Perseids - from Comet 109P Swift-Tuttle
    • Northern Taurids - Debris from Comet Encke. The Taurids and Encke are thought to be part of a much larger comet that disintegrated over the past 20,000-30,000 years. Planetary perturbations have split the debris stream into two observable showers (Northern & Southern).
    The 2013 data only covers the latter part of the year. The following meteor showers showed significant increasing fireball numbers for 2014 as compared with 2013, but showed no significant increase for 2015 vs 2014:
    • Geminids - Unlike most meteor showers, the Geminids are not associated with a comet but with Asteroid 3200 Phaethon
    • Perseids - Comet 109P Swift Tuttle
    • Orionids - Debris from Comet 1P Halley
    • Sigma Hydrids - Showed increasing Fireball numbers across each year
    • Sigma Hydrids - Faint shower. The meteors are said to have a "Perseid-type velocity." It is assumed that the source was a long-period comet and these are the last remnants of its tail
    Keep in mind, however, that the vast majority of fireballs are classed as 'sporadics', i.e. they are not identified with any known meteor shower. They may occur during the same time period as a named meteor shower, but travel in different directions and occur in different parts of the sky.


    © Dr. M.A. Rose - NASA's identification of fireballs since October 2013. Note that the vast majority of them could not be associated with known meteor streams...

    [see original article for more diagrams]


    © Dr. M.A. Rose - From 2013 to 2014 NASA registered a 2-fold increase in fireballs identified as Taurids. From 2014 to 2015 there was a more then 3-fold increase

    2015 finished with about 20% more fireballs compared to 2014:

    What's up (in space)?

    So it appears that one of a couple of things is happening:
    • The solar system is moving into an area of space where it is encountering a higher density of rocks/asteroids, along with the debris trails of some comets, e.g. Encke
    • Or something a la 'Nemesis'5 is approaching the inner solar system and perturbing comets/asteroids from the Kuiper Belt and/or the Oort Cloud.
    • The two scenarios are not mutually exclusive: the first scenario could also trigger the second.
    The 'Nemesis' hypothesis6,7 proposes that the Sun has a companion star - a brown or red dwarf - in a highly elliptical orbit that periodically disturbs comets/asteroids in the Oort Cloud, causing a large increase in the number of comets visiting the inner solar system, and a consequential increase in impact events on Earth.

    No 'Nemesis' twin sun has yet been detected by NASA's WISE (Wide-field Infrared Survey Explorer) telescope - or so we're told - but WISE has discovered several brown dwarfs in neighboring star systems.8

    More recently, Napier et.al.9 published a paper highlighting the significance of Centaurs in the Oort Cloud. Centaurs are giant comets in the trans-Neptunian region, which if displaced into the main solar system, could disintegrate and lead to intermittent but prolonged bombardment of inner solar system planets, for up to 100,000 years. Their opening paragraph is worth reproducing here:
    Quote Do we live in dangerous times? The risks to civilization from impacts by asteroids and comets have been appreciated only in the past few decades. Programmes such as NASA's Spaceguard observations seek to map near-Earth objects (NEOs) as a way to quantify the risk to Earth. But does the current count of NEOs reflect the population over time? We argue that the population is variable and that assessments of the extraterrestrial impact risk based solely on near-Earth asteroid counts underestimate its nature and magnitude for timescales of order 10,000 years, i.e. the interval of interest and concern to our civilization.

    A more variable but significant threat comes from Centaurs, giant comets derived from the trans-Neptunian region that reach the inner solar system generally via short-term, dynamically unstable residence periods in the outer planetary region. The disintegration of such giant comets would produce intermittent but prolonged periods of bombardment lasting up to 100,000 years. Mass extinction/geological boundary events on Earth show such a pattern, as do levels of dust and meteoroids in the upper atmosphere. Over the past 10,000 years, Earth has been experiencing the intermittent arrival of dust, meteoroids and comet fragments from the disintegration of comet 2P/Encke, trapped within the orbit of Jupiter.
    Napier et al further noted that, "All three major 20th-century impacts (Tunguska, British Guiana, Curuca River) coincided with our passage through major meteoroid streams (respectively, the Beta Taurids, Geminids and Perseids)." We currently have significant increases in fireballs among the Perseids and Northern Taurids.

    I guess we shall just have to see what 2016 has in store, but so far, in early January, the pattern already appears to be... continued increase in fireballs:

    One dies as ‘meteorite’ falls in Vellore

    By A.D. Balasubramaniyan and S. Vijay Kumar

    Updated: February 7, 2016 05:32 IST


    The crater formed after the object, believed to be a meteorite, fell on the campus of Bharathidasan Engineering College, near Natrampalli, in Vellore on Saturday.

    One person was killed and three others were injured when an object believed to a meteorite fell on the campus of a private engineering college near Natrampalli in Vellore district in northern Tamil Nadu early on Saturday.

    According to police sources, a loud blast was heard near a water tank shortly after midnight on the Bharathidasan Engineering College premises in K.Bandarappalli village. Kamaraj, a college employee, who had gone to drink water suffered serious injuries and was declared dead when taken to the Vaniyambadi Government Hospital. Three others suffered minor injuries. Window panes and wind screens of buses parked nearby and the water tank were broken in the impact of the blast. A crater was formed at the site of blast.

    Though there was suspicion that it was a bomb blast, preliminary investigation by forensic and bomb experts showed no sign of any explosive substance at the scene. Pieces of a rare kind of stone were found and samples taken for analysis by scientists.

    “We can rule out the possibility of any terror angle or sabotage. Not a single ingredient pertaining to any kind of explosive was found at the site. We suspect it to be a meteorite fall,” a top police official told The Hindu on Saturday. After a similar blast was reported in a paddy field at Alangayam in the same district on January 26, a senior Astrophysicist of the National Physical Laboratory, Ahmedabad, came to the district for a study. “The scientist was camping nearby and rushed to the college soon after hearing the news of the blast. We are convinced that it is a meteorite that fell with high velocity. In the earlier incident, local people remember having seen an object falling from the sky in the field,” the official said.

    A special team of the Bomb Detection and Disposal Squad, led by Deputy Superintendent of Police Asir Vijay Kumar, inspected the scene and ruled out the use of grenades. Vellore Superintendent of Police Senthilkumari also visited the spot. Investigators were trying to check if the college had any CCTV camera covering the disturbed area.

    Meteor explodes over Denmark with meteorite found

    Sott.net Mon, 08 Feb 2016 11:42 UTC



    © Frank Weinberger privat. Night sky illuminated in Ballerup, Denmark

    Hundreds of Danes reported the sky was suddenly lit up and a loud bang followed shortly after what most likely was a meteor streaking the sky over Copenhagen at around 10:08 pm Saturday 6. of February, 2016. The meteor was also spotted from Poland and Sweden.

    Bo Michael Hansen from Roskilde wrote on TV 2 News' Facebook-profile:
    Quote " Bright flash, very loud boom followed by a long lasting rumble for 20-30 seconds, at Roskilde. Birds awoke and started chirping in the gardens and nearby wetlands. As a part time fire fighter I was on my way out of the door, as I thought it was a powerful explosion."
    Anette Glentvor in Vesterbro wrote:
    Quote "The sky was gradually lit fully up. After that the sky turned green and ended with a short purple flash. About five minuttes after a long rumbling was heard. It sounded like thunder, except that the sound continued for a very long time."
    Mikkel Pedersen from Roskilde told DR:
    Quote "We were driving home from Hillerød to Roskilde, when at 10 pm we were just outside Slangerup and a strong light suddenly lit up the sky and a huge fireball with a long tail flew right above our car,"
    .
    A meteorite at about 50 g was found by a woman who was out for a smoke in Ejby, on the outskirts of Copenhagen. It will be on display at The Geological Museum between 4-6 PM, today Monday 8. February, before it is sent to Italy for tests.

    Update:

    Meteorites by the kilos have been found on the outskirts of Copenhagen. Some will be on display at the Geological Museum between 4-6 PM, today, Monday 8th February, before being sent to Italy for tests.

    New dating technique shows multiple meteors struck the Earth 790,000 years ago

    by Chuck Bednar, Red Orbit, February 23, 2016


    A new analysis of tektites, gravel-sized objects made of natural glass and formed from terrestrial debris ejected when meteorites collide with the Earth’s surface, has revealed that multiple cosmic impacts took place in various parts of the world approximately 790,000 years ago.

    Dr. Mario Trieloff, a geoscientist at Heidelberg University in Germany, and his colleagues used a new, more accurate dating technique based on naturally-occurring isotopes to investigate rock glasses retrieved from various locations in Asia, Australia, Canada, and Central America.

    As they report in a paper to be appear in the April 2016 edition of Geochimica et Cosmochimica Acta, the samples are all virtually identical in age, despite the fact that, in some cases, they have significantly different chemistry. This indicates that a series of separate impact events must have occurred at roughly the same time, the study authors explained in a statement.


    Some of the tektites used in the study. Credit: Heidelberg University

    Tektites are formed when terrestrial material melts following a meteorite impact, is launched into the air and then hardens into glass, and Dr. Trieloff’s team said that they can determine when and where projectiles struck the planet’s surface, how often, and how large those objects were.

    Natural disasters, lower surface temperatures would have followed
    The researchers explained that scientists had long known about the existence of tektites in the Australasian region, from Indochina to southern Australia. Smaller rock glass samples called microtektites were also collected in deep-sea drill cores off the coast of Madagascar and in the Antarctic, and samples from Central America and Canada were analyzed as well.

    Dr. Trieloff, lead author Dr. Winfried Schwarz and their fellow geoscientists used the 40Ar-39Ar dating method to analyze the decay of naturally occurring 40K isotope, and found that there must have been a cosmic impact approximately 793,000 years ago, plus or minus 8,000 years.

    Tektites from Canada were similar in terms of chemical composition to those from Australia or the Antarctic, the authors said, suggesting that they may have traveled the same “flight routes,” provided the recovery sites were actually where the rock glass samples landed. The composition of the tektites recovered from Central America differed from the others, however.

    “These tektites are clearly different in their chemical composition, and their geographical distribution also shows that they come from separate impacts,” said Dr. Schwarz. “Surprisingly our age estimates prove that they originated 777,000 years ago with a deviation of 16,000 years. Within the error margin, this matches the age of the Australasian tektites.”

    “The distribution of the tektites and the size of the strewn field indicate that Earth-striking body was at least a kilometer in size and released an impressive one million megatons of TNT energy within seconds of impact,” the doctor added. Such an impact would have had dire consequences, as it would have caused widespread fires, earthquakes and/or tsunamis, and the amount of dust ejected into the atmosphere would have blocked sunlight and lowered surface temperatures.

    Comet (Siding Spring's) Punch Threw Mars' Magnetism into Chaos

    By Ian O'Neill Mar 10, 2016 01:35 PM ET


    This artist's impression depicts Comet Siding Spring narrowly miss Mars in 2014. NASA/JPL-Caltech

    When Comet C/2013 A1 (Siding Spring) swung past the Red Planet in October 2014, it was an unprecedented opportunity for an armada of Mars robots to have a ringside seat of the interplanetary spectacle. But as dazzling as the flyby was, the real drama wasn’t seen by the cameras of Mars orbiters or rovers; it was detected by a magnetometer. And that magnetometer, located 100 miles above the Martian surface, detected chaos.

    “Comet Siding Spring plunged the magnetic field around Mars into chaos,” said Jared Espley, of NASA’s Goddard Space Flight Center in Greenbelt, Md. and science team member of NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft, in a NASA press release. “We think the encounter blew away part of Mars’ upper atmosphere, much like a strong solar storm would.”

    Although Mars’ magnetic field is weak and patchy (unlike Earth’s strong, global magnetosphere), MAVEN’s sensitive magnetometer detected a huge upheaval in orbit as Siding Spring’s own magnetism rattled the planet’s magnetic field.

    The comet’s nucleus may only be a third of a mile wide, but the atmosphere surrounding the nucleus (known as the coma) was as wide as 600,000 miles when it encountered Mars. (The coma is formed through solar heating — the ices contained within a comet’s nucleus sublimate into space, pumping the coma with gas.) Through interactions with the solar wind, comets also generate their own magnetic fields that loop their way through the coma. So when Siding Spring buzzed Mars, coming as close as 87,000 miles, the cometary magnetism punched Mars’ weak magnetic field, sending it into violent turmoil for several hours.

    MAVEN scientists likened the effect as a magnetic curtain flapping in the wind.

    “The main action took place during the comet’s closest approach,” said Espley, “but the planet’s magnetosphere began to feel some effects as soon as it entered the outer edge of the comet’s coma.”

    These magnetic observations were very lucky as MAVEN had only just arrived in Mars orbit weeks before the close encounter. Although most of the spacecraft’s instruments were powered down at that time (to protect them from possible damage by comet dust), the magnetometer remained on for the duration, carrying out unique observations of two magnetic fields slamming into one another.

    “With MAVEN, we’re trying to understand how the sun and solar wind interact with Mars,” added Bruce Jakosky, MAVEN’s principal investigator from the University of Colorado in Boulder. “By looking at how the magnetospheres of the comet and of Mars interact with each other, we’re getting a better understanding of the detailed processes that control each one.”

    We now know that Mars’ atmosphere is slowly leaking into space as its magnetic field isn’t strong enough to completely protect it from solar wind erosion. And, from these MAVEN measurement, it looks like this magnetic “hit and run” by Siding Spring also ripped a chunk out of the Red Planet’s atmosphere, giving us a profound look at what happens when comets and planets (almost) collide.


    The close encounter between comet Siding Spring and Mars flooded the planet with an invisible tide of charged particles from the comet’s coma. The dense inner coma reached the surface of the planet, or nearly so. The comet’s powerful magnetic field temporarily merged with, and overwhelmed, the planet’s weak field, as shown in this artist’s depiction.

    Space rock relic: Scientists say new type of meteorite is remnant of ancient asteroid collision

    A meteorite discovered in a Swedish quarry appears to be the only remnant of one part of a massive asteroid collision more than 470 million years ago, according to new research.

    Scientists at the University of California, Davis have published their findings on the unique space rock discovered in 2011 in the journal Nature Communications.

    The meteorite is the first of its kind found on Earth. "In our entire civilization, we have collected over 50,000 meteorites, and no one has seen anything like this one before," said study co-author Qing-zhu Yin.

    "Discovering a new type of meteorite is very, very exciting," he added.

    The fossilized remains of the meteorite, named Österplana 065 (Öst 65) after a church close to its discovery, was found in in Sweden’s Thorsberg quarry five years ago. The quarry has so far been the source of more than 100 common fossil meteorites called “L type chondrites.”

    However, scientists noted that this meteor, just 4 inches wide and with an appearance described as “gray cow patty plopped into a pristine layer of fossil-rich pink limestone,” was unique.


    The meteorite is 8 × 6.5 × 2 cm large. It is surrounded by a grey reduction halo, in the otherwise red limestone. Oxygen was consumed when the meteorite weathered on the sea floor. The coin in the image has a diameter of 2.5 cm. © Nature Communications

    The researchers found it was chemically distinct from not only the other meteorites found in the quarry, but also from the thousands of meteorites previously analyzed.
    Researchers now believe the rock resulted from an ancient asteroid collision during the Ordovician Period, leading to the fall of many L type chondrites from one of the asteroids – but mostly obliterating the other asteroid.

    The Öst 65 appears to be the only trace of the mystery object on Earth, but scientists say it’s possible that its remains are still out in space.

    They measured the cosmic ray exposure of Öst 65 and found it had traveled in space for about a million years before striking Earth some 470 million years ago. This indicates it may be a fragment of the impact asteroid that broke up the L-chondrite parent body, scientists concluded, noting the timeline matches up with L-chondrite meteorites found in the quarry.

    The study supports previous research linking the meteorite to a “major collisional event” and strengthens suspicions that more recent meteorites which have fallen on Earth do not represent the full range of rocks out there in our solar system.

    “The meteorites found on Earth today apparently do not give a full representation of the kind of bodies in the asteroid belt 500 million years ago,” the study says.

    Yin said it is possible to gain a better understanding of our solar system by analyzing meteorite fragments preserved in Earth’s ancient rocks: “If we can go back even further in time, we may eventually be able to find some of the true building blocks of Earth.”

    Researchers say this may be the first documented example of an “extinct” meteorite – no other meteorite from that asteroid will fall on Earth again as its parent body has been “consumed by collisions.”

    If we were to take Mark Richards, Charles Forte, Robert Morningsky and Ed Grimsly into account, then we may very well be seeing some kind of hot war going on. The increase in falling debris may very well be the product of space faring vehicle blasted into our atmosphere. Could this be various agencies of the secret space programs at odds with one another? Or could there be some type of alien vs secret space program scenario or alien vs alien? I do not know, but regardless, this may be more than space rock or space debris being responsible for the uptick in meteors blazing across our sky.

    'Meteorite' crashes through Phitsanulok house roof

    PHITSANULOK - A mysterious rock, believed to be a meteorite, crashed through the roof of a house in Phitsanulok's Muang district on Tuesday.

    The suspected meteorite fell through the roof of a home in Plai Chumphon sub-district at 7.26am, hit a wall and then bounced to the floor, breaking into five pieces.

    “I was having breakfast when there was a loud bang, like a gunshot sound. I looked around and found a rock about the size of an egg and some fragments nearby. I picked up the largest chunk and let go quickly as it was very hot,” 65-year-old home-owner Bualom Chalomprai said.

    Mrs Bualom believes the rock is from outer space and will bring her good luck.

    Mrs Bualom’s husband, Kittisak, 75, said he heard a sound of explosion in the sky at about 7am before the 300g rock fell through his roof.

    Media reports said residents in adjacent districts of Nakhon Thai and Chat Trakan also heard the "explosion".

    Scientists at Naresuan University’s department of physics later carried out an initial examination on a small fragment taken from the Chalomprai family home and concluded the object could very likely be a meteorite given its features and the circumstance under which it had been found.

    Department head Sarawut Tuantam said the rock’s crust was charcoal black, indicating it had been burned entering Earth's atmosphere at very high speeds. The test also found the chunk contained large amount of iron and was attracted by a magnet.

    Prof Sarawut added that the Chalomprais could keep the suspected space rock as it had safe radioactivity levels.

    Justinian’s Raging Bulls

    By malagabay Posted on May 1, 2016



    The Plague of Justinian has been associated with the extreme weather events of 535–536 AD which [in its turn] has been associated with “debris from space impacting the Earth”.
    Quote The extreme weather events of 535–536 were the most severe and protracted short-term episodes of cooling in the Northern Hemisphere in the last 2,000 years.

    The event is thought to have been caused by an extensive atmospheric dust veil, possibly resulting from a large volcanic eruption in the tropics, and/or debris from space impacting the Earth.

    Its effects were widespread, causing unseasonal weather, crop failures, and famines worldwide.

    https://en.wikipedia.org/wiki/Extrem...35%E2%80%93536

    The Plague of Justinian (541–542) was a pandemic that afflicted the Eastern Roman (Byzantine) Empire, especially its capital Constantinople, the Sassanid Empire, and port cities around the entire Mediterranean Sea.

    One of the greatest plagues in history, this devastating pandemic resulted in the deaths of an estimated 25 million (initial outbreak) to 50 million (two centuries of recurrence) people.

    Recent investigations relate this severe plague epidemic to extreme weather events of 535–536 considered as an example of volcanic winter.
    https://en.wikipedia.org/wiki/Plague_of_Justinian
    In a wonderful YouTube video Ruth Dwyer examines the Ravenna Mosaics and discovers the mosaics clearly depict “debris from space impacting the Earth”.

    Quote Ravenna is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Italy.

    It was the capital city of the Western Roman Empire from 402 until that empire collapsed in 476.

    It then served as the capital of the Kingdom of the Ostrogoths until it was re-conquered in 540 by the Eastern Roman (Byzantine) Empire.
    Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the invasion of the Franks in 751, after which it became the seat of the Kingdom of the Lombards.
    https://en.wikipedia.org/wiki/Ravenna

    Ruth Dwyer finds [amongst other things] that the Ravenna Mosaics depict: fiery clouds, shock waves, raining fire and a blue Sun.
    Fiery Clouds


    Shock Waves


    Raining Fire


    Blue Sun


    Ruth Dwyer also finds that many of these phenomena were documented by contemporary authors.
    Quote 25. Senator, Praetorian Praefect, to his Deputy Ambrosius, an Illustris.

    [This letter appears to have been written in the early autumn of 538, about a year after the three last letters, and also after Letters 27 and 28, which precede it in order of date, though they follow it in this collection. For an account of the terrible famine in Italy, the beginning of which is here described, see Procopius, De Bello Gotthico ii. 20.]

    Famine in Italy
    ‘Since the world is not governed by chance, but by a Divine Ruler who does not change His purposes at random, men are alarmed, and naturally alarmed, at the extraordinary signs in the heavens, and ask with anxious hearts what events these may portend.

    The Sun, first of stars, seems to have lost his wonted light, and appears of a bluish colour.

    We marvel to see no shadows of our bodies at noon, to feel the mighty vigour of his heat wasted into feebleness, and the phenomena which accompany a transitory eclipse prolonged through a whole year.
    ‘ The Moon too, even when her orb is full, is empty of her natural splendour.

    Strange has been the course of the year thus far.

    We have had a winter without storms, a spring without mildness, and a summer without heat.

    Whence can we look for harvest, since the months which should have been maturing the corn have been chilled by Boreas ?

    How can the blade open if rain, the mother of all fertility, is denied to it ?

    These two influences, prolonged frost and unseasonable drought, must be adverse to all things that grow.

    The seasons seem to be all jumbled up together, and the fruits, which were wont to be formed by gentle showers, cannot be looked for from the parched earth.

    But as last year was one that boasted of an exceptionally abundant harvest, you are to collect all of its fruits that you can, and store them up for the coming months of scarcity, for which it is well able to provide.

    And that you may not be too much distressed by the signs in the heavens of which I have spoken, return to the consideration of Nature, and apprehend the reason of that which makes the vulgar gape with wonder.

    ‘ The middle air is thickened by the rigour of snow and rarefied by the beams of the Sun.

    This is the great Inane, roaming between the heavens and the earth.

    When it happens to be pure and lighted up by the rays of the sun it opens out its true aspect ; but when alien elements are blended with it, it is stretched like a hide across the sky, and suffers neither the true colours of the heavenly bodies to appear nor their proper warmth to penetrate.

    This often happens in cloudy weather for a time ; it is only its extraordinary prolongation which has produced these disastrous effects, causing the reaper to fear a new frost in harvest, making the apples to harden when they should grow ripe, souring the old age of the grape-cluster.

    ‘All this, however, though it would be wrong to construe it as an omen of Divine wrath, cannot but have an injurious effect on the fruits of the earth.

    Let it be your care to see that the scarcity of this one year does not bring ruin on us all.

    Even thus was it ordained by the first occupant of our present dignity, that the preceding plenty should avail to mitigate the present penury.’

    However, after a nudge from CW, I took a closer look and noticed the Ravenna Mosaics also contain a very clear indication that the “debris from space” was “coming on us from the stars” in the Taurus constellation.

    Quote
    Taurus
    is one of the constellations of the zodiac, which means it is crossed by the plane of the ecliptic.

    Taurus is a large and prominent constellation in the northern hemisphere’s winter sky.

    It is one of the oldest constellations, dating back to at least the Early Bronze Age when it marked the location of the Sun during the spring equinox.

    Its importance to the agricultural calendar influenced various bull figures in the mythologies of Ancient Sumer, Akkad, Assyria, Babylon, Egypt, Greece, and Rome.
    https://en.wikipedia.org/wiki/Taurus...nstellation%29
    Unsurprisingly, the Taurus constellation is associated with the annual Taurids Meteor Shower which is linked to Comet Encke [orbital period: 3.3 years] that is believed to be remnants of a much larger comet which has disintegrated.

    Quote A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky.

    These meteors are caused by streams of cosmic debris called meteoroids entering Earth’s atmosphere at extremely high speeds on parallel trajectories.
    https://en.wikipedia.org/wiki/Meteor_shower

    The Taurids are an annual meteor shower associated with the comet Encke.

    They are named after their radiant point in the constellation Taurus, where they are seen to come from in the sky.

    Because of their occurrence in late October and early November, they are also called Halloween fireballs.

    Encke and the Taurids are believed to be remnants of a much larger comet, which has disintegrated over the past 20,000 to 30,000 years, breaking into several pieces and releasing material by normal cometary activity or perhaps occasionally by close encounters with the tidal force of Earth or other planets (Whipple, 1940; Klačka, 1999).

    In total, this stream of matter is the largest in the inner solar system.
    Since the meteor stream is rather spread out in space, Earth takes several weeks to pass through it, causing an extended period of meteor activity, compared with the much smaller periods of activity in other showers.

    The Taurids are also made up of weightier material, pebbles instead of dust grains.
    https://en.wikipedia.org/wiki/Taurids

    Comet Encke or Encke’s Comet (official designation: 2P/Encke) is a periodic comet that completes an orbit of the Sun once every 3.3 years.

    Comet Encke is believed to be the originator of several related meteor showers known as the Taurids (which are encountered as the Northern and Southern Taurids across November, and the Beta Taurids in late June and early July).
    https://en.wikipedia.org/wiki/Comet_Encke
    But given the orbit of Comet Encke its origins are far more likely associated with a planetary explosion that occurred in the Titius–Bode Gap between Mars and Jupiter.

    Quote However, an examination of the Jupiter-family trajectories clearly indicates a convergence point [just beyond the current orbit of Mars] which strongly suggests these comets had an explosive origin in the very recent astronomical past.

    See: The Other Big Bang Theory
    https://malagabay.wordpress.com/2013...g-bang-theory/
    Either way, its worth taking another look at the temperature record used by Ruth Dwyer in her The Comet of 536 and the Ravenna Mosaics video [at 12:07] to see if there is any evidence of a very short period comet or the disintegration of a short period comet.

    Framingham man believes meteorite pinged pear tree

    By Rob Haneisen Daily News Staff
    Posted Sep 6, 2016 at 3:27 PM
    Updated Sep 6, 2016 at 5:22 PM


    FRAMINGHAM - First a late hard freeze robbed Steven Lovewell's Asian pear tree of most of its blossoms. Then the summer drought wiped out all but one lonely pear ripening on his tree. The final blow came swiftly and loudly - from a meteorite.

    Lovewell, who lives on Grant Street, said he was awakened by a loud whooshing noise about 3 a.m. Tuesday. Later that morning he found his one Asian pear fruit on the ground with what he believes is a meteorite embedded in its flesh. The dark rocky object, about the size of a peach pit, protruded about halfway from the fruit.

    Lovewell said he has been interested in astronomy and rocket science since he was a kid. He plans to reach out to the McAuliffe Center at Framingham State University to try and confirm his belief that his last Asian pear was knocked from the tree by an extraterrestrial object. In the meantime, the pear and meteorite are chilling in his freezer for safe keeping.

    30 Tons Meteorite Found In Gancedo, Argentina

    Posted: Sep 13 2016, 12:06am CDT | by IANS,
    Updated: Sep 13 2016, 9:05am CDT,

    The Gancedo meteorite is the world's second largest meteorite ever discovered.

    Scientists have discovered a meteorite weighing over 30 tons in northern Argentina on September 10.

    The meteorite was found in the town of Gancedo, 1,085km north of capital Buenos Aires, Mario Vesconi, President of the Astronomy Association of Chaco, said on Monday.


    "While we hoped for weights above what had been registered, we did not expect it to exceed 30 tons," Vesconi said, adding that "the size and weight surprised us", Xinhua news agency reported.

    "It was in Campo del Cielo, where a shower of metallic meteorites fell around 4,000 years ago," Vesconi added.

    The meteorite will be weighed again to ensure an accurate measurement.

    The largest meteorite ever found is called Hoba, weighing 66 tons in Namibia, Africa.

    Update with additional details on the Gancedo Meteorite
    The Gancedo Meteorite is believed to be the second largest meteorite ever discovered. A previously discovered meteorite in the El Chaco area weight 28.84 tons. The researchers had to be very careful in recovering the metallic meteorite because of the ground water coming into the crater according to Argentina newspaper La Nacion.

    Now Argentina has two of the world's largest meteorites. Only the Hoba meteorite discovered is larger with 66 tons. There are possibly more meteorites to be discovered in the El Chaco area.

    A huge meteor passed over the north east of Algeria,at 21:22 pm yesterday , Saturday 01/10/2016.

    Here is a mobile recorded video shows the fireball over Constantine.

    A second video is from cctv cam in Ain MELILA region.

    Rumours indicate that it fell in the surroundings whereas nearby cities have witnessed an impact shock .

    IMO this is what the DUMBS are for, there's no way you can logically look at history & not see that impacts from space are the very highest of threats that we face.

    Meteorites pummel the Moon far more than expected

    Hundreds of fresh impact craters hint at possible dangers for future lunar bases.

    Alexandra Witze 12 October 2016



    NASA/GSFC/Arizona State University: A new lunar crater, formed about three years ago.

    Meteorites have punched at least 222 impact craters into the Moon's surface in the past 7 years. That’s 33% more than researchers expected, and suggests that future lunar astronauts may need to hunker down against incoming space rocks.

    “It's just something that's happening all the time,” says Emerson Speyerer, an engineer at Arizona State University in Tempe and author of a 12 October paper in Nature1.

    Planetary geologists will also need to rethink their understanding of the age of the lunar surface, which depends on counting craters and estimating how long the terrain has been pummeled by impacts.

    Although most of the craters dotting the Moon's surface formed millions of years ago, space rocks and debris continue to create fresh pockmarks. In 2011, a team led by Ingrid Daubar of NASA’s Jet Propulsion Laboratory in Pasadena, California, compared some of the first pictures taken by NASA’s Lunar Reconnaissance Orbiter (LRO), which launched in 2009, with decades-old images taken by the Apollo astronauts. The scientists spotted five fresh impact craters in the LRO images. Then, on two separate occasions in 2013, other astronomers using telescopes on Earth spotted bright flashes on the Moon; LRO later flew over those locations and photographed the freshly formed craters2, 3.

    Forever young
    LRO has taken about a million high-resolution images of the lunar surface, but only a fraction cover the same portion of terrain under the same lighting conditions at two different times. Speyerer’s team used a computer program to automatically analyse 14,092 of these paired images, looking for changes between the two. The 222 newfound craters are distributed randomly across the lunar surface, and range between 2 and 43 metres in diameter.

    There are more fresh craters measuring at least 10 metres across than standard cratering calculations would suggest. This could mean that some young lunar surfaces may be even younger than thought, says Daubar. She calls the work “a significant advance in the field of crater chronology”, noting that it can even be used to compare cratering rates on the Moon and Mars.

    Meteorites can churn up the lunar surface in several ways. Along with the fresh craters, Speyerer's team found more than 47,000 ‘splotches’, formed when material gets kicked up by the main impact and rains down — sometimes tens of kilometres away.

    And that means a bigger risk for any future lunar habitats, says Stephanie Werner, a planetary geologist at the University of Oslo. The chances of a lunar base being nailed by a direct meteorite hit are relatively small, but the splattered material could pose a hazard. Werner is part of a team that has proposed a combined orbiter–lander mission to the European Space Agency, which would study impact flashes at the Moon and quantify the risk.

    The meteor is picking up traction!! 13%, that's higher than Gary Johnson!




    This is BY FAR the biggest threat to humanity, I think all military spending should be globally combined to "astroid hunters" or some sort of "us v them" that puts all humans on the same side.

    Meteor fireball filmed over Cordova, Spain

    Meteors You Tube Thu, 27 Oct 2016 20:33 UTC


    This fireball was observed over the South of Spain on Oct. 26, at 23:57 UT (1:57 local time on Oct. 27).

    The event was produced by a sporadic cometary meteoroid that hit the atmosphere at about 94000 km/h.

    The fireball began at a height of 90 km over the province of Cordoba and ended at a height of 40 km over the Mediterranean Sea.
