The Upcoming Celestial Events thread

[Orion11]

Hey all,

I find myself often wanting to post astronomy related things going on in the skies, and instead of making a new thread for every event,
I figured it would be good to have one thread where anyone can post any upcoming events they come across.

cool? or not cool? :mfr_lol:

To start it off, Tonight right after Sunset, about 9pm,

http://www.astronomy.com/asy/default.aspx?c=a&id=8172

See Mercury, the Moon, and the Pleiades together in the night sky
http://www.astronomy.com/asy/objects/images/april-2009-stm-mercury-find.jpg

Don't miss a stunning sight around 9 P.M. local daylight time April 26 when a crescent Moon joins Mercury and the Pleiades in the deepening twilight.

Mercury puts on a fine show starting the second week of April, and you won't have to get up early or venture far to see it.

In mid-April, Mercury sets more than 80 minutes after sunset. During the month's final 2 weeks, Mercury closes in on the spectacular Pleiades star cluster, also known as the Seven Sisters.

Astronomy magazine Contributing Editor Raymond Shubinski encourages everyone to observe Mercury. "Mercury is a major planet in our solar system," he says. "Everyone who's interested in the sky should see it at least once. And when the planet's bright like it is now, all it takes is a quick trip outdoors."

Don't miss a stunning sight around 9 P.M. local daylight time April 26 when a crescent Moon joins Mercury and the Pleiades in the deepening twilight. The Moon lies 2° (about 4 Moon-widths) above the cluster, and Mercury sits 3° (6 Moon-widths) below the cluster. The Moon's dark portion will be clearly visible, illuminated by sunlight reflected from Earth, known as earthshine. Binoculars will provide the best view.

On April 29, Mercury lies about 3 Moon-widths south of the Pleiades. The Moon has climbed significantly higher and will lie in the constellation Gemini the Twins. Mercury has dimmed to the brightness of Aldebaran, the nearby reddish 1st-magnitude star in the constellation Taurus.

Viewing Mercury through a telescope remains challenging. The planet's disk reveals little. Its low altitude in the sky and its visibility shortly after sunset leave observers viewing the disk while Earth's atmosphere remains turbulent. The unsteady air yields unsteady images.

Still, Mercury's appearance changes noticeably each evening. On April 9, 90 percent of the planet's disk was illuminated. You'll hardly notice it as less than full. The phase shrunk to three-fourths lit by April 15 and to half-phase April 21. By month's end, Mercury will display a 27-percent-lit crescent.

Sgr A* - known by the Maya as "Hunab Ku"
'The Great Central Sun' of the Galaxy

http://chandra.harvard.edu/photo/2003/0203long/0203long_xray.jpg


This Chandra image of the supermassive black hole at our Galaxy's center, a.k.a. Sagittarius A* or Sgr A*, was made from the longest X-ray exposure of that region to date. In addition to Sgr A* more than two thousand other X-ray sources were detected in the region, making this one of the richest fields ever observed.

During the two-week observation period, Sgr A* flared up in X-ray intensity half a dozen or more times. The cause of these outbursts is not understood, but the rapidity with which they rise and fall indicates that they are occurring near the event horizon, or point of no return, around the black hole.

Absolutely, a good idea. It will be interesting to see other contributions

thanks ladies, and bro. :D :wub2:

Jrod.. that is an amazing image!!!!!!

not sure ive seen that one,
i got another one that reminds of this one, from its description, Ill try to find it.

that is beautiful man!! :wub2:
thanks for sharing,
i to look forward to what will be shared in this thread. :D

i love yas. <3

Ad Astra per Aspera!*

p.s.. that image reminds me of being born for some reason. lol

[Orion11]

ahhh,
here it is , friends...
http://upload.wikimedia.org/wikipedia/commons/thumb/c/c5/Milky_Way_Galaxy_center_Chandra.jpg/800px-Milky_Way_Galaxy_center_Chandra.jpg

Original caption:

This 400 by 900 light-year mosaic of several Chandra images of the central region of our Milky Way galaxy reveals hundreds of white dwarf stars, neutron stars, and black holes bathed in an incandescent fog of multimillion-degree gas. The supermassive black hole at the center of the Galaxy is located inside the bright white patch in the center of the image. The colors indicate X-ray energy bands - red (low), green (medium), and blue (high).

The mosaic gives a new perspective on how the turbulent Galactic Center region affects the evolution of the Galaxy as a whole. This hot gas appears to be escaping from the center into the rest of the Galaxy. The outflow of gas, chemically enriched from the frequent destruction of stars, will distribute these elements into the galactic suburbs. Because it is only about 25,000 light years from Earth, the center of our Galaxy provides an excellent laboratory to learn about the cores of other galaxies.

LOVE the Mosaic, good find Orion11

Here are two nebula East and West of Sgr A* =

This oval, shell-like feature is thought to be a supernova remnant, material from which may help fuel an accretion disk. (The red point in the image is the Sgr A* radio source.)

Sgr A* West =
Recent observations of atomic hydrogen gas suggest that some of these filamentary structures are part of massive cloud falling in toward the Galactic Center.

O! rhythmm

absolutly

lovin


this

one :thumb_yello::thumb_yello::thumb_yello:

keep it comin

and thankyou :wub2::wub2::wub2:

[burgundia]

wonderful idea. I'll be checking the thread regularly.

[Orion11]

:wub2:

I was just out there a minute ago, and i got Jupiter and all its moons in the eyepiece!!!
lol, first time ive gotten that!!
woot!! :D:thumb_yello:

I could see the bands, the storm (red spot) and all its Moons... man.. soo very cool! . lol
I watched it for over an hour, until it got to light out and it was drowned out.

I got some pics to, they are on the cam, ill se ehow they came out before i go showin em. lol

I just pulled this out of my stellarium... (the stars look extra big due to shining, in the program i guess, thr the scope they were alot finer and smaller than Jupiter. lol)
http://projectavalon.net/forum/attachment.php?attachmentid=799&stc=1&d=1240826863
and made it the same size as i saw it thru the scope, with the 9mm eyepiece.. just for kicks, really. :mfr_lol:

But this is what ive been staring at..
making contact, in a sense.. lol

Edit: dang... does anyone else find it kind of annoying that we can only upload one pic per post? ive never personally seen that on any other forum.... its always at least 3.. and most of em like 10.. so we gotta make seperate posts in order for seperate pics... .. and they are also resized wicked small when uploaded thru the post. lol

ok, sorry for that.. just had to get it out. :mfr_lol:

hahahahahahaha!!!!! :D

thats funny man.......

just the other day... i said to a friend and his girlfriend...

"hey... look at that star!!!!" (i even kinda pointed) LOL

and they both looked all around for a bit.., and said.. "wheree??!??"

lmaoo!!

haha, awesome bro!
what size scope? i wanna get a max-cass onea thse days..
when i fully learn the art of material manifestation. lol

the synchronicity(s) are always at work ...
everyday they show more n more.

so.. fur shur!! haha. :)

thanks bro. :wub2:

[Gemeos]

Hi Orion,

Thank You for opening this thread. I love Astronomy!
Every time I can, I go up to the country and do some night-sky observations with my 10x50 binoculars. It's great.

This is a must-read thread!:thumb_yello:

Best

http://antwrp.gsfc.nasa.gov/apod/image/0904/ngc4565_ritter.jpg (http://antwrp.gsfc.nasa.gov/apod/image/0904/ngc4565_ritter_big.jpg)

Explanation: Is our Galaxy this thin? We believe so. Magnificent spiral galaxy NGC 4565 (http://www.seds.org/messier/xtra/ngc/n4565.html) is likely similar to our own spiral galaxy, but viewed edge-on from far away. Also known as the Needle Galaxy (http://antwrp.gsfc.nasa.gov/apod/ap990617.html) for its narrow profile, bright NGC 4565 (http://en.wikipedia.org/wiki/NGC_4565) is a stop on many telescopic tours (http://www.youtube.com/watch?v=_IB1JNn694E) of the northern sky as it lies in the faint but well-groomed constellation Coma Berenices (http://www.dibonsmith.com/com_con.htm). This sharp color image (http://www.darkatmospheres.com/astro/gallery/galaxies/enlarge.php?fileBase=galaxies_5) reveals the galaxy's bulging central core dominated by light from a population of older, yellowish stars. The core is dramatically cut by obscuring dust lanes (http://antwrp.gsfc.nasa.gov/apod/ap070729.html) which lace NGC 4565's thin galactic plane (http://antwrp.gsfc.nasa.gov/apod/ap020703.html). NGC 4565 lies about 30 million light-years (http://chandra.harvard.edu/photo/cosmic_distance.html) distant and spans over 100,000 light-years in diameter. Visible through a small telescope (http://antwrp.gsfc.nasa.gov/apod/ap050413.html), some sky enthusiasts (http://www.astronomy2009.org/globalprojects/cornerstones/galileoscope/) consider NGC 4565 (http://www.noao.edu/outreach/aop/observers/n4565.html) to be a prominent celestial masterpiece Messier missed (ftp://ftp.seds.org/pub/info/newsletters/WASP/wasp_mmm.html#8).

http://antwrp.gsfc.nasa.gov/apod/image/0904/prometheusring_cassini.jpg (http://antwrp.gsfc.nasa.gov/apod/image/0904/prometheusring_cassini_big.jpg)

Explanation: What's causing those strange dark streaks in the rings of Saturn? Prometheus (http://en.wikipedia.org/wiki/Prometheus_(moon)). Specifically, an orbital dance involving Saturn's moon Prometheus (http://www.planetary.org/explore/topics/saturn/prometheus.html) keeps creating unusual light and dark streamers in the F-Ring (http://en.wikipedia.org/wiki/Saturn%27s_rings#F_Ring) of Saturn. Now Prometheus (http://antwrp.gsfc.nasa.gov/apod/ap041217.html) orbits Saturn just inside the thin F-ring (http://www.planetary.org/explore/topics/saturn/rings.html), but ventures into its inner edge about every 15 hours. Prometheus' gravity then pulls the closest ring particles (http://www.youtube.com/watch?v=6JdzjXlvBYE) toward the 100-km moon. The result is not only a stream of bright ring particles (http://antwrp.gsfc.nasa.gov/apod/ap050525.html) but also a dark ribbon (http://antwrp.gsfc.nasa.gov/apod/ap081208.html) where ring particles used to be. Since Prometheus (http://www.youtube.com/watch?v=bKhYSv3FZP4) orbits faster than the ring particles, the icy moon pulls out a new streamer every pass. Sometimes, several streamers or kinks (http://en.wikipedia.org/wiki/File:Prometheus_tugging_on_F_Ring_PIA09909.jpg) are visible at once. The above photograph (http://photojournal.jpl.nasa.gov/catalog/PIA10593) taken in mid-January by the robotic Cassini Spacecraft orbiting Saturn. The oblong moon Prometheus is visible on the far left of the image.

[Orion11]

damn thats sweet Dan!! :D

the pic of Saturns rings.. to the top left....
almost looks like a 'worm hole' opening up... or closing. lol

cuz you know.. ive seen soo many in my life! LOL

thanks bro

[Dantheman62]

http://antwrp.gsfc.nasa.gov/apod/image/0904/img8188_lawrence.jpg (http://antwrp.gsfc.nasa.gov/apod/image/0904/img8188_lawrence.jpg)

Explanation: Last Sunday's fading evening twilight featured a young crescent Moon along the western horizon. The young Moon also shared the sky with the lovely Pleiades star cluster (http://antwrp.gsfc.nasa.gov/apod/ap081209.html) and wandering planet Mercury (http://antwrp.gsfc.nasa.gov/apod/ap080127.html). Framed by clouds in this serene skyscape (http://spaceweather.com/submissions/large_image_popup.php?image_name=Pete-Lawrence-2009-04-26_MoonMercury_800_IMG_8163_1240783615.jpg) from Selsey, UK, a similar twilight scene was visible around the globe. Emerging from the cloud bank below the Pleiades, the narrow sunlit lunar crescent (http://antwrp.gsfc.nasa.gov/apod/ap090424.html) is overexposed. Still, the Moon's dim night side is impressively clear, illuminated by earthshine (http://science.nasa.gov/headlines/y2005/04oct_leonardo.htm). Bright, innermost planet (http://messenger.jhuapl.edu/index.php) Mercury lies near the bottom of the field. Mercury will remain near the Pleiades, low in the west (http://www.earthsky.org/skywatching/mercury-pleaides-low-in-western-sky-at-dusk) after sunset over the coming days, an ongoing conjunction of planet and star cluster that will offer skygazers some excellent binocular views.

[raulduke]

cool? or not cool? :mfr_lol:

Definitely cool. :thumb_yello: Thx bro!

Dan, I check out APOD often too (got it on my iphone), great site.

You guys hear about this gamma ray burst photograph?

http://apod.nasa.gov/apod/image/0904/grb8_gemini.jpg

GRB 090423: The Farthest Explosion Yet Measured
Credit: Gemini Observatory / NSF / AURA, D. Fox & A. Cucchiara (Penn State U.), and E. Berger (Harvard Univ.)
Explanation: An explosion so powerful it was seen clear across the visible universe was recorded in gamma-radiation last week by NASA's orbiting Swift Observatory. Farther than any known galaxy, quasar, or optical supernova, the gamma-ray burst recorded last week was clocked at redshift 8.2, making it the farthest explosion of any type yet detected. Occurring only 630 million years after the Big Bang, GRB 090423 detonated so early that astronomers had no direct evidence that anything explodable even existed back then. The faint infrared afterglow of GRB 090423 was recovered by large ground telescopes within minutes of being discovered. The afterglow is circled in the above picture taken by the large Gemini North Telescope in Hawaii, USA. An exciting possibility is that this gamma-ray burst occurred in one of the very first generation of stars and announced the birth of an early black hole. Surely, GRB 090423 provides unique data from a relatively unexplored epoch in our universe and a distant beacon from which the intervening universe can be studied.

Seems significant maybe.

[Gemeos]

Hey Dan,

Great photos! Thanks!

The Universe is such a great "Show", and people aren't aware of it!

Hey Yo Orion,
My Max/Cass is a 127-mm diameter Primary mirror, with total Focal L. at 1540-mm. The f=12.1, and is equivalent to ~350x without the Barlow multipliers; also a full spectrum of filters. Haven't got a camera for it yet.

Dantheman,
Great shot there of NGC 4565. That's one I don't yet have on my walls. And, yes, it is said that our own galaxy is as thin as a pancake if viewed on edge.

Raulduke,
That massive Gamma-burster very likely when the first Galaxies and Stars were forming from primordial Hydrogen. There were no heavier elements around then, so Stars could grow to HUMONGOUS size (a technical term). Someone asked me about that one once, and following is a little write-up I gave 'em...:

An explosion of that magnitude is most likely produced by the Collapsar event of a HYPERNOVA STAR. HyperNovas result from HyperMassive single Stars which are in the range of 120 to 160 Solar Mass. Such stars are also 'First-Generation' stars within young, newly forming Galaxies. (Remember, we are also looking backwards in Time 12.2-Billion+ years, or more). When such HyperMassive Stars collapse, they instantly form a "Black Hole" with all the equivalent mass of 120 to 160 Suns all converted to Pure Energy (There is no MASS or Matter "inside," only Energy equal to the Mass times the speed of Light squared, E=MC^2, a truly HUGE amount of energy).

SuperNova Stars, which are more common, are generally in the range of 10 to 30 Solar Masses. SuperMassive Collapsars also instantly form "Black Holes."

Our Sun (equal = 1-Solar Mass) is a 'Third-Generation' Star, since it has accumulated all the elements higher than Iron (on the periodic chart) within itself, which were produced in the explosions of 'ordinary' Nova Stars - having less than 3-Solar Mass, and distributed throughout it's collected planets (Terra, Mars, Pluto, Malona, &c). First Generation Stars, on the other hand, accumulate only from coalescing huge cloud-masses of Hydrogen with some Helium, and with no heavier elements, when they ignite by Fusion into the Star. With no heavy elements to begin with, is the reason such Stars can grow so large. We don't see such HyperMassive Stars in our neighborhood, as these are in the first evolution phase of young Galaxies.

When ANY Star collapses into a "Black Hole," all of the Stars' Angular Momentum is converted into Spin. Then all the Energy inside the Event Horizon is now spinning at a very high 'velocity' which, like a monstrous Electro-Magnetic Generator, Polarizes the "Hole" (creates a pair of poles) which focuses Energy from the Accretion Disk, where the remaining mass of the Star from it's outer 'shell layers' is still being converted into Energy.

"Black Holes" with Jets are in the 'Feeding' stage. Ours, at the Core of our Galaxy, is currently in a 'Quiescent Mode.' (But there are signs that it may begin soon to feed again.)

These Focused beams include extremely Energetic Gamma, and also lesser energetic Energy down through X-Ray bands, Visual Light bands, and all down into the Radio-Frequency bands - all this in a continuous spectrum. It is ONLY when the Polarization Axis is pointed directly in our direction, are we able to "see" them. Like having the barrel of the Canon pointed at us. "Black Holes" and their Galaxies are oriented in every possible direction. Therefore, for each one that we do see, there are hundreds of thousands more which we can't see (Ratio less than 1/100,000), but they ARE there too.

Oh, and thinking about "Black Holes," some new theories have proposed there are micro-holes, little balls of energy with strong gravity, smaller then a proton. There's supposed to be Gazillions of these (High-Math here). But myself, I think this theory is full of holes. Anyway, here's artist conceptions of one of these micro-beasties...:

http://www.ecopolis.org/wp-content/uploads/2007/10/071012_miniblackholes_hmed_2phmedium.jpg

A micro black hole, also called a quantum mechanical black hole and inevitably a mini black hole, is simply a tiny black hole for which quantum mechanical effects play an important role.
http://www.ecopolis.org/in-space-happens-strange-things/


And this next is a concept of Gravity Waves...:

http://www.ecopolis.org/wp-content/uploads/2007/10/071012_gravitywaves_hmed_2phmedium.jpg

In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from a moving object or system of objects. Gravitational radiation is the energy transported by these waves. Important examples of systems which emit gravitational waves are binary star systems, where the two stars in the binary are white dwarfs, neutron stars, or black holes.

i love you guys/gals.. thanks soo much!!

great stuff!!

Here is the new Sky map for May 2009
http://www.skymaps.com/downloads.html

scroll down and choose your hemisphere and the PDF will open for you...

Each month the new one can be found there...

i have located many galaxies and messier objects using these maps, that i wouldnt have been able to find otherwise..
(until i learn its whole computer thing, then i can just tell it where to look) lol

and from sky and telescope...

http://media.skyandtelescope.com/images/WebVic09_May1.jpg
#

Friday, May 1

# First-quarter Moon (exact at 4:44 p.m. EDT).

# Mayday is also known as Beltane, for the ancient Gaelic festival that gave rise to some of our May Day traditions. Beltane is one of the four cross-quarter days about midway between the equinoxes and solstices. In other words, this is the midpoint of spring (Northern Hemisphere spring).

More or less. The actual midpoint between this year's March equinox and June solstice comes on May 5th, at 4:45 p.m. Eastern Daylight Time.


http://media.skyandtelescope.com/images/WebVic09_May3.jpg
# Saturday, May 2

# The Moon shines about 3° below Regulus during evening for North America, as shown at right.

# Venus in the morning sky is at its greatest illuminated extent: when its sunlit area appears to be largest as seen in a telescope (when it shows the most illuminated square arcseconds). This is about when Venus is at its greatest brilliancy.


dang.. i just lost a bunch of stuff in this post... grrrr.... lol

[Orion11]

J Rod, that scope sounds great!!!

i just got my first scope for Xmas, 5 inch meade newt.

do you ever do any astrophotography?

[Malynda]

dang.. i just lost a bunch of stuff in this post... grrrr.... lol

I didn't get lost. I may have wandered off the path and started thinking about other interesting things that your post conjured. lol I started thinking about Venus (love) and Mars (war) being so close to each other from our vantage point. Then I was thinking about 05/05/2009 at 4:45pm and all the other interesting coincidences, patterns, etc. that I have been seeing lately (or imagining lol). It was a great post and I shall be watchful for the beauty of the heavens that day. Thanks for taking the time to share that information. :original:

Not really on topic, but here's a little info on Hubble!...........

Servicing Mission 4 — the fifth and final visit to Hubble,

1 May 2009
On 11 May, Space Shuttle Atlantis will launch with a crew of seven to visit the NASA/ESA Hubble Space Telescope and carry out the fifth and final servicing mission. The replacement and repair of several instruments will see Hubble equipped to continue its programme of discovery well into the next decade.

The combination of Hubble's powerful suite of instruments and its location far above Earth's atmosphere has consistently produced outstanding scientific results for 19 years. This success is due to both the robust initial design of the satellite and the remarkable series of servicing missions that have kept the complex operating platform functioning and up to date.

Astronauts from NASA and ESA visited Hubble in 1993, 1997, 1999 and 2002, carrying out a series of repairs and upgrades on each occasion. During the upcoming Servicing Mission 4 (SM4) astronauts will carry out five spacewalks to complete one last set of improvements. This will mean that every major component on the spacecraft, apart from the mirrors, will have undergone at least one upgrade since launch.

THREE CHEERS for Hubble, an amazing Telescope.


Hubble captures views of mammoth stars

http://www.esa.int/images/heic0822a_M.jpg

Two of our galaxy's most massive stars, until recently shrouded in mystery, have been viewed by the NASA/ESA Hubble Space Telescope, unveiling greater detail than ever before.

The image shows a pair of colossal stars, WR 25 and Tr16-244, located within the open cluster Trumpler 16. This cluster is embedded within the Carina Nebula, an immense cauldron of gas and dust that lies approximately 7500 light-years from Earth. The Carina Nebula contains several ultra-hot stars, including these two star systems and the famous blue star Eta Carinae, which has the highest luminosity yet confirmed. The the Eta Carinae Nebula is much less well known, due to its location far in the southern hemisphere.

We are thankful for the Hubble Scope for this image. The true color of these Stars is an amazing joy to see. For a Beautiful High-Res view, go to this address and click on the photo...:

Hubble sees magnetic monster in erupting galaxy

http://www.esa.int/images/heic0817a_L.jpg

The Hubble Space Telescope has found the answer to a long-standing puzzle by seeing the details of giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275.

These filaments are the only visible-light manifestation of the intricate relationship between the black hole hosted at the centre of the galaxy and the surrounding cluster gas. They provide important clues about how giant black holes affect their surrounding environment.

The core is dramatically cut by obscuring dust lanes (http://antwrp.gsfc.nasa.gov/apod/ap070729.html) which lace NGC 4565's thin galactic plane (http://antwrp.gsfc.nasa.gov/apod/ap020703.html). NGC 4565 lies about 30 million light-years (http://chandra.harvard.edu/photo/cosmic_distance.html) distant and spans over 100,000 light-years in diameter. Visible through a small telescope (http://antwrp.gsfc.nasa.gov/apod/ap050413.html), some sky enthusiasts (http://www.astronomy2009.org/globalprojects/cornerstones/galileoscope/) consider NGC 4565 (http://www.noao.edu/outreach/aop/observers/n4565.html) to be a prominent celestial masterpiece Messier missed (ftp://ftp.seds.org/pub/info/newsletters/WASP/wasp_mmm.html#8).

Something I've always wondered - Can anyone explain how we get such pictures looking AT our galaxy when no man made object has seemingly left out galaxy?

I can understand how we could see objects looking OUT from the galaxy but how have they managed to do the reverse? i.e. Looking at our galaxy from the outside...

Thanks :original:

Hey Iain,

well, they really , truly do not know what our Mily Way galaxy looks like from the outside...

I recently read something on a science site...

that said many scientists now believe our Galaxy to actually have only 2 arms,
rather than 4 as previously thought.

interesting eh?

Iain, Quote under the photo: "Magnificent spiral galaxy NGC 4565 is likely similar to our own spiral galaxy,..."

No, WE don't have any photos of our own Galaxy from anywhere but from here at Earth. If anyone "out-there" has any such photos, they haven't shared them with us. I wish they would share everything they have with us, but we shall just have to be patient.

Hey Orion + Jrod - thanks for clearing that up :thumb_yello:

That is interesting Orion yes. Are there any examples we know of out there of a galaxy only having 2 arms? :original:

[Orion11]

hey there bro.. you are welcome... :)

and yep.. there are many actual pictures of real galaxies that have only 2 arms...

Here is a couple..

its got some interesting stuff!!..

Scientists Now Know: We're Not From Here!

Summary & comments by Dan Eden for Viewzone

Imagine the shock of growing up in a loving family with people you call "Mum" and "Dad" and then, suddenly, learning that you are actually adopted!

This same sense of shock came as scientists announced that the Sun, the Moon, our planet and its siblings, were not born into the familiar band of stars known as the Milky Way galaxy, but we actually belong to a strange formation with the unfamiliar name of the Sagittarius Dwarf galaxy!

How can this be?

Using volumes of data from the Two-Micron All Sky Survey (2MASS), a major project to survey the sky in infrared light led by the University of Massachusetts, the astronomers are answering questions that have baffled scientists for decades and proving that our own Milky Way is consuming one of its neighbors in a dramatic display of ongoing galactic cannibalism. The study published in the Astrophysical Journal, is the first to map the full extent of the Sagittarius galaxy and show in visually vivid detail how its debris wraps around and passes through our Milky Way. Sagittarius is 10,000 times smaller in mass than the Milky Way, so it is getting stretched out, torn apart and gobbled up by the bigger Milky Way.
http://www.viewzone.com/milkyway1.jpg

A new infra red digital survey of the entire sky was made in 2003. Teams from the universities of Virginia and Massachusetts used a supercomputer to sort through half a billion stars to create a -- NEW STAR MAP showing our Solar System (yellow circle) to be at the exact nexus crossroads where two galaxies are actually joining.

"It's clear who's the bully in the interaction," said Steven Majewski, U.Va. professor of astronomy and lead author on the paper describing the results.

"If people had infrared-sensitive eyes, the entrails of Sagittarius would be a prominent fixture sweeping across our sky," Majewski said. "But at human, visual wavelengths, they become buried among countless intervening stars and obscuring dust. The great expanse of the Sagittarius system has been hidden from view."

Not any more. By using infrared maps, the astronomers filtered away millions of foreground stars to focus on a type of star called an M giant. These large, infrared-bright stars are populous in the Sagittarius galaxy but uncommon in the outer Milky Way. The 2MASS infrared map of M giant stars analyzed by Majewski and collaborators is the first to give a complete view of the Milky Way galaxy's meal of Sagittarius stars, now wrapping like a spaghetti noodle around the Milky Way. Prior to this work, astronomers had detected only a few scattered pieces of the disrupted Sagittarius dwarf. Even the existence of Sagittarius was unknown until the heart of this nearest satellite galaxy of the Milky Way was discovered by a British team of astronomers in 1994.

PHOTO IN THE NEWS: Milky Way's Turbulent Core in Hi-Res

http://imgsrc.hubblesite.org/hu/db/images/hs-2009-02-d-xlarge_web.jpg

January 6, 2009—The first infrared panorama of the Milky Way's center (detail of the full panorama (http://hubblesite.org/newscenter/archive/releases/2009/02/image/d/format/xlarge_web/) above) has revealed a previously unknown population of massive stars (http://science.nationalgeographic.com/science/space/universe/stars-article.html) scattered across the turbulent zone around our galaxy's core.
A composite of Hubble and Spitzer space-telescope observations, the panorama covers a 300-by-115-light-year area with a high enough resolution that—even at a distance of 26,000 light-years from Earth—objects as small as 20 times the size of our solar system are brought to light. Among these object are about 26 million stars, 300 of which can be identified as massive stars that are relatively young—a few million years old or less. About two-thirds of those 300 are single stars that are unexpectedly lying outside the three known clusters of star formation.

What’s Up This Month - June 2009

June 2, 2009

As June arrives, the galaxy fields of spring slowly give way to the beautiful overhead arc of the Milky Way. On June 6, a nearly-full Moon passes in front of a bright red supergiant star in Scorpius. All planets are visible this month, though only Saturn is found in the evening sky.

For observers in the northern hemisphere, the sun lies high in the sky during the day and not far below the horizon at night, which makes for long twilight and short nights. Summer arrives at 5:46 GMT on June 21. But the days now– slowly at first– start getting shorter. (Of course, it’s the other way around for observers in the southern hemisphere).

Life is busy, I know. But try to get out to enjoy a few moments of stargazing. Let a few rays of ancient starlight strike your eye and incite your imagination.

Celestial Events in June

Moon occults Antares. In the evening of June 6, in the Caribbean, northern parts of Latin America, and all but northeastern and far western North America, the nearly-full Moon occults the bright supergiant star Antares in Scorpius. It should be quite a show. This month, you can see the dramatic rise of Scorpius in the late evening as it lurches over the south-eastern horizon, claws first, looking for its prey.

Io and Ganymede cast shadows simultaneously on the face of Jupiter from 8:06 to 10:16 Greenwich Mean Time (GMT) on June 9. A small telescope at 100x or more should give you a good view. Click here to translate Greenwich Mean Time to the time in your area. The event will look a little like this…YouTube - Jupiter Double Transit



Pluto lies directly opposite the Sun this month in northern Sagittarius. At 14th magnitude, it lies beyond the sight of all but the most determined stargazers.
Moon and Planets

The Moon. Full on June 7; new again on June 22. On June 19, as a thin waning crescent, the Moon is just 6-7 degrees above Venus and Mars in the pre-dawn sky.

Venus. The beautiful planet wheels away from the Earth and dims slightly in the morning sky. On June 6, the Sun illuminates only half of the face of Venus as seen from the Earth.

Mars. Lies about 10 degrees above the eastern horizon early in the month, rising a little higher towards the end.

Saturn follows Leo into the southwest after sunset. But it’s still putting on a good show. The rings tilt just 3 degrees from edge on. Regulus lies west of Saturn and Spica lies further east. Saturn is the one that doesn’t twinkle.

Jupiter. The king of planets lies in eastern Capricorn, low in the sky for northern observers again this year. Observe it carefully on nights with steady seeing, when the image of the planet doesn’t seem to “boil” in your field of view. As mentioned above, in a telescope, you can see a double shadow on the planet on the morning of June 9.

Neptune. Fairly dim at 8th magnitude. Even a good-sized telescope will struggle to show Neptune’s disk, which is only 2.3″ across. But the outer planet is less than 0.5 degrees from Jupiter all month, so you can see them in a single low-power field of view.

Uranus rises a couple hours after midnight. It’s in Pisces, near the “circlet” of stars that makes up the head of the western “fish”. It’s visible in a telescope before the sun rises.

Deep-Sky Sights

The fine double star Izar (epsilon Bootis) is well worth a look. Separated by just 3″, you’ll need decent seeing and a magnification of 100x or so to resolve the pair. The reward for your effort is the sight of a splendid contrast of color and brightness. The brighter star has exhausted its fuel and become a bright red-orange giant; the fainter is a bright white main sequence star which still burns hydrogen in its core. The pair lies about 200 light years away and takes more than 1,000 years to revolve around each other.

For southern observers, try Acrux (alpha Crucis), the magnificent double star at the foot of the Southern Cross. Acrux is actually a triple. The main pair, stars A and B, are brilliant blue-white, and separated by 4″. C is nearly 5th magnitude some 90″ away. The widely separated A and C components are visible in 10×50 binoculars, and a 3-inch scope shows the A-B pairing at 70x or more.

And finally, June’s Astronomy Haiku…


Darkness falls later,

hey kids,

In case anyone didnt get to see the Moon occult Antares last night,
Here are a few shots I got thru my scope.
