Hubble finds ghostly object in deep space
There's a green blob in space, but unlike a bad science fiction movie, it's not coming to take over Earth. Probably.
The Hubble Space Telescope has captured an image of a green cloud of gas about 650 million light-years from Earth. It's been named Hanny's Voorwerp, Dutch for Hanny's Object.
The object is illuminated by a beam of light from a quasar that may have gone dark 200,000 years ago, according to the Space Telescope Science Institute in Baltimore.
The Voorwerp is about the size of our Milky Way galaxy and is part of a 300,000-light-year-long stream of gas, the institute says. The green color is from glowing oxygen.
What appears to be a gaping hole in Hanny's Voorwerp actually may be a shadow cast by an object in the quasar's light path, according to the institute.
"This phenomenon is similar to a fly on a movie projector lens casting a shadow on a movie screen," the institute says.
The object may have been formed by a collision of two galaxies, according to the institute.
But don't worry. It won't bump into our galaxy within our lifetime.
Probably.

Next it is time to beat on the other parts of this articles innacuracy... The visible portion of this oddity (the green glowing part) is only 92,000 light years long, or roughly the size of the Milky Way Galaxy. The entire oddity is about 300,000 light years long, including the non-visible portion. It wraps around it's associated galaxy (IC 2497). The interesting part of this, part of what the Hubble was looking for, is that the upper yellow and orange part of the glowing portion is filled with ongoing star birth. The associated quasar is NOT in fact in the oddity, but in the nearby galaxy core. The large dark spot in the center is a "shadow effect" due to interference between the quasar and the oddity. The evidence is supported by a massive outflow of gas and particles from the core visible only to space based telescopes, an outflow caused by a quasar fueled by the influx of matter near a black hole. The quasar "flashed on" once enough matter was collected causing a massive burst of light, illuminating the oddity. Then 200,000 years ago (or, if you are looking for true numbers, 650,200,000 years ago real time) the quasar "shut off" and what we see now is the remanent of the burst of light.
The oddity was discovered in 2007 by a school teacher in the Netherlands who was assisting in the Galaxy Zoo project. The teacher, Hanny van Arkel, spotted it in an image taken during the Slaon Digital Sky Survey. The name Hanny's Voorwerp means "Hanny's Object" in Dutch. Recently a lot of the worlds telescopes and sensors were pointed at this thing, with the best images of course coming from Hubbles Wide Field Camera 3 and Advanced Camera for Surveys.
I use the term oddity because there is no true classification for this type of stellar object yet, other than tidal tail.
My appologies for the massive post that re-states the article. I had started typing it, and was double checking my facts, when the article was updated. There are a few more details, like where the quasar is and the means by which the discovery was made. I didn't mention the theory that the Voorwerp is possibly the remanent of two galaxies colliding, which is again supported by visible evidence in the near-by galaxy (twisting in the spiral arms of the galaxy, and unsetteled dust lanes). This collision is also possibly what provided the matter required by the quasar to create the outburst of light that is iluminating the Voorwerp in this image.
Thanks for a "real" enlightening article!
You have tooo much free time on your hands.
Guys this was obviously a typo, and an attempt at humor. The author should simply make the corrections and we all move on. No worries.
OK, OK. Enough of bashing the author. Yes, originally the article stated 300,000 miles rather than 300,000 light years. But to say that the author didn't know what he was talking about is going over the top. It may have been just an inadvertant error. I agree that the proof reading should have caught the error, but it didn't. That doesn't mean the author didn't know that the galaxy is larger than 300,000 miles. We all make mistakes.
People who know science/space do not confuse miles with light years, nor do they think the size of the Milky Way Galaxy is 300,000 miles (or even 300,000 light years), which was what was originally implied. So, thank you, but I'm going to keep my opinion that the author truly doesn't know what he is talking about. However, even if it was an inadvertent error, then Mr. Kavanagh fails Journalism Grammar 101 for constructing such a poor sentence. Either way, FAIL.
Wait, so what you're saying is don't make fun of this guy because he wrote an article about something he knows nothing about?
The headline is also wrong. It was discovered (found) by Hanny Van Arkel while working on GalaxyZoo phase 1.
GalaxyZoo is a citizen science project. It developed into zooniverse.org which is an umbrella org for several citizen science project. Yahoo.com has a better article about this.

Very amusing to see how STUPID many who post on this are. Did ANY of you make it through high school? For crying our loud the article CLEARLY states 300,000 LIGHT YEARS across, NOT 300,000 miles. One more time LIGHT YEARS across, you freaking dolts, lol. Jeex Lueez READ people just READ.
again: perhaps it says that because the article was corrected? unlike your newspaper, they can change stuff on the internet.
@PCola Vet
When I saw the article a few hours before your post it said 300,000 miles. You would think that whoever edited the article would at least provide the time of update when they corrected it...especiially after all the comments on the accuracy of the article. Not much journalistic integrity there....
Wait, you honestly thought that EVERYONE made the exact same mistake, and mistook lightyears for miles? And you're calling us stupid...
iit's just hal jordan learning to use his powers as green lantern duhh!!! you can't even have privacy in space. damn you hubblee!!!! 🙂
Nope..it was kryptonite, Superman will be in deep trouble.
looks like when I check for worms after i'm donw with number 2opppaaaa my mom would be proud
I love the big hole in the middle.. It's like a blackhole..
Everything scientific is related to comic books these days. Eventually your face will be a comic book.
That's where the Norway Spiral came from!! Neato!
jehovah god created the universe and the earth,he knows every star by name..says it in the bible.....
george that is most ridiculous and pointless post I have seen all day. Might want to try a new approach to recruitment.
Thanks PVS, didn't know the article had been corrected.
Well measurements aside I believe we have found some vespene gas. As a starcraft fan this is the first thing I thought of after reading this.
true. No chance of harvesting it tho, as we would need vespene first to make the proper stargate. we will be stuck on mass marines forever, stuck on our island xpax
I think we've wasted our supply limit on marines, ghosts and nukes. Damn newbs!!!
Best comment so far.
To the believers and non-believers, please answer these questions.
If God created the universe, who created God? God all of a sudden appeared from nothing? Very difficult to believe or understand, unless you just believe.
If everything was started from the Big Bang, what was there 1 second before the Big Bang? Did the Big Bang and all the matter start from nothing? Don't say gravity started it, even if you are the greatest scientist living today. That is too funny.
Can we just say we simply don't know and may never know, atleast not yet? May be our brain is not capable of understanding everything just as an animal is not capable of understanding to the level we do.
There are folks who will bring this discussion up in ANY thread. How do we know you're not just trolling?
Stephen Hawking can anwer this better. He claims that the universe is capabale of spontaneous creation. At the same time, the beauty of creation is that it nevertheless does permit for the possibility of G_d...to discover that, one necessarily needs to look within - "The answer's at the end."
There was no 1 second before the big bang as time did not exist. Gravity did not cause it and it had no mass.
What was one second before the big bang? Two membranes colliding. Read M-Theory. It's great stuff.
See? That's what hatches from inside of a planet. A green monster.. That sure explains all the earthquakes lately. 🙂 Sleep tight!
God is three persons in One body. Therefore, based on methodical conversion that's how it all got started. Trigonometry my friend.
Honestly, who cares if god exists or not? I just think it's cool that stuff like this exists and that we can look at it. Why drag god into it all? Let's just enjoy the fact that we have more mysteries to solve in the Universe, than we would ever be capable of solving, and that's great news, because it means that the wow effect will never wear off for our species.
I agree if god created everything who created god ? and what did happen before the big bang? Is it possible that we are inside a black hole since black holes are port holes to other places. Or is it possible that there are other universes outside of ours that created this univese since everything has a start point and everything has a end point is it possible that our universe does too unless it is round like a sphere in that case there is no end point or beginng point. Its whatever you want to think but i dont think humans have developed the capibility to figure out what did happened yet in this time period all people can do is put the pieces to the puzzle together until the answer is revealed.
Am I the only one who sees the resemblance to His Noodliness?? Ramen!
No one created God, he's always been there. Silly...
its called faith
THE BIG BANG CREATED TIME...THEREFORE THERE IS NO "1 SEC BEFORE THE BIGBANG".THE BIG BANG WAS CREATED BASED ON QUANTUM PHYSICS IN WHICH MATTER APPEARS AND DISAPPEARS RANDOMLY...IT IS POSSIBLE THAT A LARGE AMOUNT OF MATTER AND ANTI-MATTER APPEARED SIMULTANIOUSLY AND CREATED THE BIG BANG.AS FAR AS "GOD" IS CONCERNED....IT IS A GREAT FAIRY TALE ABOUT SOME SKY WIZARD
IF GOD IS 3 PERSONS IN 1 BODY THEN THAT IS A FORM OF SPLIT PERSONALITY WHICH SUGGEST INSANITY...HMMMM
Well at least scientists are making progress explaining everything, whereas the 'science' of God seems to be chipped away at at the same pace science makes real progress. Earth isn't flat anymore, is it?
There is speculation about 'white holes' – the other end of a black hole. The big bang may have come when a super white hole formed. And it's all speculation. We don't know enough to answer competently. But speculation and reasoning is fun. (until religion is tossed in)
Our mind is not capable, but our being is. God is the nothing that it sprang from and God is throughout. The is the closest way I can describe it, but God is understood best when felt. The infinite and the eternal.
Does he also enjoy drinking jack as much as you do?
The infinite and the eternal. To me, that would be the Goddess. It is She who gives birth.
Agree with Eliz – if 'god' is Mother Nature, physics, cause and effect – I'm there with you.
(correction) That is the closest....
as a Human You were never ment to understand the beginning of God. The creation of God if any or if he has always been. Your puny Mind/ Brain CAN never comprehend that. Ever!
Your comment just proved that!
He?
Yes, god can only be understood by the special.. the elite.. the chosen ones.. (crank up the final countdown on the radio)
@Weallhaveone
He? What, do you think God's a girl or something? The Bible refers to him as He. He is used to show whether it is male, or unigender. Duh.
can god make a burrito so hot that even he cannot eat?
A Voorwerp is not a weapon it's a tool, like a hammer or a screwdriver or an alligator
haha
Out of all the comments i read so far here..this one made me stop and think.
why do religious nuts flock to science articles ?
why do science nut's flock to religion articles.
because it's fun speaking from authority about something they have never studied except from a few hours of Mr Wizard on TV.
That's awesome
