    Default Interstellar object ’Oumuamua confirmed to be from another solar system

    Astronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1(’Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighbourhood.



    The certainty of its extraterrestrial origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.

    Its name comes from a Hawaiian term for messenger or scout. Indeed, it is the first space rock to have been identified as forming around another star. Since asteroids coalesce during the process of planet formation, this object can tell us something about the formation of planets around its unknown parent star.

    The latest analyses with ground-based telescopes show that ’Oumuamua is quite similar to some comets and asteroids in our own solar system. This is important because it suggests that planetary compositions like ours could be typical across the galaxy.

    It is thought to be an extremely dark object, absorbing 96% of the light that falls on its surface, and it is red. This colour is the hallmark of organic (carbon-based) molecules. Organic molecules are the building blocks of the biological molecules that allow life to function.

    It is widely thought that the delivery of organic molecules to the early Earth by the collision of comets and asteroids made life here possible. ’Oumuamua shows that the same could be possible in other solar systems.

    Its characteristics have been published by two independent groups of astronomers. The first group, led by Karen Meech, University of Hawaii, also found that ’Oumuamua was extremely elongated and roughly 400 metres long. Using the European Southern Observatory’s Very Large Telescope(VLT) they also found that it rotated once every 7.3 hours.

    The other group of astronomers, led by David Jewitt, University of California Los Angeles, estimated how many other interstellar visitors like it there might be in our solar system.

    Surprisingly, they calculate that another 10,000 could be closer to the Sun than the eighth planet, Neptune, which lies 30 times further from the Sun than the Earth. Yet these are currently undetected.

    Each of these interstellar interlopers would be just passing through. They are travelling too fast to be captured by the gravity of the Sun. Yet it still takes them about a decade to cross our solar system and disappear back into interstellar space.

    If this estimate is correct, then roughly 1,000 enter and another 1,000 leave every year – which means that roughly three arrive and three leave every day.

    Using robotic telescopes such as Pan-STARRS, the one that detected ’Oumuamua, to look for asteroids is a priority for astronomers as they concentrate on discovering potentially hazardous objects that could impact Earth.

    Imminent upgrades to these survey telescopes and improvements in data processing techniques mean that astronomers will soon be able to detect smaller and fainter objects. They expect a number of these to be interstellar interlopers like ’Oumuamua.

    First Interstellar Asteroid Wows Scientists

    NASA Jet Propulsion Laboratory

    https://www.youtube.com/watch?v=fbL1ZoAQgUU

    Published on 20 Nov 2017
    Scientists were surprised and delighted to detect --for the first time-- an interstellar
    asteroid passing through our solar system. Additional observations brought more
    surprises: the object is cigar-shaped with a somewhat reddish hue. The asteroid,
    named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long
    and highly-elongated—perhaps 10 times as long as it is wide. That is unlike any
    asteroid or comet observed in our solar system to date, and may provide new clues
    into how other solar systems formed. For more info about this discovery, visit https://go.nasa.gov/2zSJVWV .

    =============================================

    Oumuamua asteroid unlike any object ever seen before

    https://www.youtube.com/watch?v=nbwYCnLm1hU

    Published on 23 Nov 2017...CNN
    On October 19, the Pan-STARRS 1 telescope in Hawaii spotted something
    strange zooming through our solar system. It turned out to be a visitor from
    beyond our solar system, and it's unlike anything astronomers have seen before.

    It is the first observed object from outside our solar system, according to a study
    published Monday in the journal Nature -- and, as the researchers call it, an "oddball."

    Thanks, LadyM, for J.L. Walson video! Who would have thunk it?!!! One of them reminded me of a craft reported being seen in Israel years ago that was shaped like a big house! Can't believe Walson is allowed to circulate the pictures! Must be some "protection" over him!

    Has anyone observed if it's travelling 'head-on' as in the same direction as it's shape, or in some other way ?

    Is it stable ?

    Is it spinning ?

    I would expect it to be spinning if it's just a lump of rock.

    Interstellar asteroid checked for alien technology
    2 hours ago



    Artwork: Observations of 'Oumuamua noted its unusual elongated shape

    A project searching for intelligent life in the cosmos is going to check the
    first known interstellar asteroid for signs of alien technology.

    The odd-shaped object was detected as it sped towards the Sun on 19 October.

    Its properties suggested it originated around another star, making it the first
    such body to be spotted in our cosmic neighbourhood. An initiative backed by
    billionaire Yuri Milner will use a radio telescope to listen for signals from it.
    The team's efforts will begin on Wednesday, with astronomers observing the
    asteroid, which is currently speeding away from our Solar System, across
    four different radio frequency bands.The first set of observations at the
    Robert C Byrd Green Bank Telescope in West Virginia is due to last for 10 hours.

    Never forget that the 'picture' of the 'asteroid' is an 'artist's representation'... it is NOT a photo of the object... You can be certain that the Real space program knows Exactly what it is, and who it is piloted by... if indeed, it is a ship and not an asteroid. Who knows?.. perhaps it's one of the 'Solar Warden' ships of the Secret Space Program. Soft disclosure???

    Note: My comment is inspired by, but not directed at Kindred's post at all ... consider it a standalone observation.


    Its never been a secret ... NASA has always used "artists rendition" or similar in any of their publications that featured a detailed picture of something ... all the way back to when I was kid -- this was the case, except the images were paintings instead of CGI.

    Of course the object is millions of miles away in pitch dark -- you can't just "snap" a photo from that distance. Even the satellites that get close to other planets have extremely complex tracking systems that allow an image to be exposed over hours or days, to compensate for the extreme lack of light - you can't do this with small fast moving objects.

    What has been the issue is people automatically believe that such an image is a photo without questioning it, and conclude that Nasa is tricking us, by supplying these images. Our own density and lack of questioning, lack of proper observing or our lack of finding original sources that have descriptions, keys, captions, disclaimers, and references, is a major contributor to the issue.

    We need to keep waking up to reality .. to things like, the reason that the vast majority photos of the Earth are collages, is because in near earth orbit, the earth takes 95% of the entire planar field of view - the only lenses capable of capturing the whole thing in one photo would be an extreme fish-eye lens. This would not be practical to use for Earth images, because of the extreme distortion these lenses cause and the lack of detail they can capture (everything looks like it is 100x farther away = no details). So if you want to capture an image of the earth without distortion and with a reasonable amount of detail, you have to use a lens with a much smaller focal length, take many images to cover the entire field of view that you want to cover in a single image, and collage the images. If one knows cameras, lenses, and what earth would look like from LEO, one can extrapolate everything I said as true.

    Sorry for the rant, but I grow a tad weary of everyone blaming some externally accepted "evil" for justifying our own shortcomings in understanding things. (Perhaps a result of observing all the FE BS)

    Not that I am saying NASA is clean with us, I know they are not on many things, but we cannot continue to use these ideas as excuses to not be able to wake up and understand the world around us. I am not writing this as seriously as it is coming across ... but do consider what I am saying.

    Cider properly included the image description for the second image ... "Artwork"

    I don't know where you heard this but I'm curious.
    Just for the record Stewart Swerdlow has mentioned that Reptilians prefer hollowed out asteroids and planetoids for use as interstellar craft. The Lacerta Interview states that Reptillians use cylendrical cigar shaped craft.
    Just throwing that out there.

    Is there any news of this object using the gravitational force of the planets to "slingshot" through our solar system? Or was it just passing through?

    'Oumuamua: 'space cigar's' tumble hints at violent past

    Artwork: The way 'Oumuamua tumbles suggests it was involved in a collision

    The space interloper 'Oumuamua is spinning chaotically and will carry on doing
    so for more than a billion years. That is the conclusion of new Belfast research
    that has examined in detail the light bouncing off the cigar-shaped asteroid from
    outside our Solar System. "At some point or another it's been in a collision," says
    Dr Wes Fraser from Queen's University. His team's latest study is featured in
    Sunday's Sky At Night episode on the BBC and published in Nature Astronomy.

    It is yet another intriguing finding about this strange object that has fascinated
    scientists since its discovery back in October. 'Oumuamua comes from a different star
    system. Its path across the sky confirms it does not originate in our solar neighbourhood.

    Similar shape to Reptilian craft !
    I don't know where you heard this but I'm curious.
    Just for the record Stewart Swerdlow has mentioned that Reptilians prefer hollowed out asteroids and planetoids for use as interstellar craft. The Lacerta Interview states that Reptillians use cylendrical cigar shaped craft.
    Just throwing that out there.
    A hollowed out asteroid would provide protection from meteorite and debris impacts and friction. Also raw material if the internal composition of the ship needs repairs (asteroids contain various metals that can be mined). It's been a proposed concept even for our own would-be manned expeditions outside the Earth's orbit.

    Interesting that they say it's come from Lyra. A place that has constantly popped up from myriad sources in regards to having human life.
    Also many of those sources also mention the places that had human life have been taken over by the reptoid species, so there's that to ponder too.



    The first thing that popped up when I first heard this story was Rendezvous with Rama by Arthur C. Clark. I wonder if this is our own RL Rama.

    Which one is ‘Oumuamua’s home star?
    September 26, 2018

    In late 2017, astronomers became aware of an interloper in our solar system, a small asteroid- or comet-like object from another star system. Interstellar objects had been expected, but this object – subsequently named ‘Oumuamua – was the first ever found. Over the past year, studies attempted to reconstruct ‘Oumuamua’s path and thereby learn its home solar system. But, until now, they hadn’t come up with plausible candidates. This week (September 25, 2018), that changed. A team of astronomers at the Max Planck Institute for Astronomy in Germany announced it has tracked ‘Oumuamua to several possible home systems. The team used data from ESA’s Gaia satellite to find four plausible stars where ‘Oumuamua could have begun its journey, more than a million years ago.

    Coryn Bailer-Jones of Max Planck led the team that managed to backtrack ‘Oumuamua’s motion and thereby to identify the four candidate stars. All four of them are dwarf stars, not surprising since dwarfs are the most common type of star in our Milky Way galaxy.

    Various studies had already suggested that ‘Oumuamua was ejected from its home star’s planetary system during the planet formation phase, when there were many small-sized objects (planetesimals) flying around that interact with giant planets in the system.

    The Max Planck team said ‘Oumuamua’s home star is likely to have two key properties. First, tracing back ‘Oumuamua’s orbit should lead directly back to, or at least very close to, the home star. Second, the relative speed of ‘Oumuamua and its home star is likely to be comparatively slow – objects are typically not ejected from their home systems at large speeds. A statement from the institute said:
    The one that came closest to ‘Oumuamua, at least about one million years ago, is the reddish dwarf star HIP 3757. It approached within about 1.96 light-years. Given the uncertainties unaccounted for in this reconstruction, that is close enough for ‘Oumuamua to have originated from its planetary system (if the star has one). However, the comparatively large relative speed (around 25 km/s [16 miles/s]) makes it less probable for this to be ‘Oumuamua’s home.
    The next candidate, HD 292249, is similar to our sun, was a little bit less close to the object’s trajectory 3.8 million years ago, but with a smaller relative speed of 10 km/s [6 miles/s].

    The two additional candidates met ‘Oumuamua 1.1 and 6.3 million years ago, respectively, at intermediate speeds and distances. These stars have been previously catalogued by other surveys, but little is known about them.
    All four of these stars remain plausible candidates, these astronomers said, but they also said:
    … the smoking gun is still missing. In order to eject ‘Oumuamua at the observed speeds, the home system would have needed to feature a suitable giant planet that could slingshot ‘Oumuamua into the depths of space.

    So far, no such planet has been detected around those stars – but since none of the stars have been examined closely for planets so far, that could well change in the future.

    This chart wasn’t part of the study of ‘Oumuamua by Bailer-Jones et al., but it gives you an idea of this object’s path through our solar system. Chart via Guy Ottewell’s blog.

    Bottom line: A team of astronomers at the Max Planck Institute for Astronomy has identified four plausible candidates for ‘Oumuamua’s host star. ‘Oumuamua is the first object from interstellar space known to have passed through our solar system.
