The BEST Hubble image is the 'Deep Field View'. You know the one with all of the galaxies?
They just pointed the telescope into empty space and they found this. If that doesn't give you a feeling of the immensity of space, I don't know what does.
Personally, I wouldn't go for any of the local planets - they've been done too much before. Judging by the eskimo nebula, nebulae are the way to go - for a little while at least. I also like the appearence of stuff when it's pouring into a black hole, just before the event horizon.

BTW, HST is not purely American.

Quite of little bit of its current funding comes from non-US sources.
A well erned victory for NASA! With all the poor press NASA has received lately with the Mars programs, it's nice to see a victory.
"Thanks to the great work by the astronauts, Hubble is better than new,"
Not only did they correct the gyro problems which made pointing a little difficult, the continued efforts on correcting the optics making them better than ever.
"After a two-month hiatus, it is a tremendous boost to all of astronomy to see Hubble back in action. Nasa has restored the observatory to a condition that was better than it was even before the fourth gyroscope failed."
This is good stuff, finally getting the 'scope up and running properly.
But its still passive observance. Not that I actually understand any of this, but wouldn't it be a good idea to spend some research dollars on a more active observation system? Impossible at today's tech level, but maybe not someday.

What do ya mean by "active observation"? I mean, there's not a whole hell of a lot we can _do_ to things that are a billion light years away. We're pretty much constrained to sit here and watch what comes our way.
There are a few other projects that will be around after Hubble (though some will go up before HST comes down) -- the Next Generation Space Telescope is the "biggest," I guess. (Other recent/upcoming telescopes, designed to look at different parts of the spectrum, include FUSE, XMM, Chandra/AXAF, etc.) One interesting bit is that there isn't currently a telescope in the works that will fully cover the HST's observation range -- that is, there are parts of the spectrum that are going to get the big 'ole shaft when HST comes down.

Bigger and better (well, mostly bigger) versions of the images can be found here and here
I always love pictures from Hubble; they are always stunningly beautiful. However, they tend to look almost *too* good, as if some graphics artist had a bit to much free time while fiddling about with The GIMP... I sometimes think the Hubble folks are trying to pull a fast one on us with these pictures:)
Heh heh heh. There _is_ some subjectivity ("artistic interpretation") that goes on... but not with any intent to mislead, just in the attempt to give the best picture. What you get from Hubble is just a CCD readout -- that is, for each filter in which you take an image, you get (roughly speaking) a number of photons for each pixel. So the image, when you look at it, is greyscale, not spiffy reds and greens and blues.
To get a color picture, you basically pick a color to go along with each filter image -- these are pretty sensible (usually), but there's still a bit of leeway. Conventional choices might be, for instance, H-alpha (H transition, at 6563 A) as red , H-beta (4861) as blue, and maybe [OIII] 5007 as green. But depending on what you wanted to show, you might choose different color-wavelength correspondences.
Also, most of the images you see in PR releases and such have probably gone through additional processes to make them look nice -- ie gaussian smoothing filters, hand-removal of pesky lingering cosmic rays, subtle implantation of subliminal messages ("hubble good. nasa good."), whatever. It's all in good fun.
I think you need to get out more and appreciate how stunningly beautiful nature actually is.:}
Seriously, though, when we do analysis, a large part of the work can be considered a form of image enhancement or image manipulation. You might spend two hours or two nights on the actual observing, and two months (or much more) on the data reduction. That tedious work makes a big difference in how good your images will be for use in actual analysis and publication, or, alternatively, how good the pretty John Q. Public version of them will look on a webpage (cummulative with, but largely independent of the quality of the actual observation). (Ah, I C while I was typing someone mentioned a few of those things that go on in optical and other regimes; I'll skip things related to that.)
Your point jogs my memory on something about NASA graphics people, tho. ("They're goood...real goood.") When I visited a digital video lab at the JPL last year or so, they showed an S-VHS of a nice fly-by of the LA basin (centered around JPL site, and sans human structures). It was about 30 sec, in 24-bit and some ridiculous 3D res, making it some 2.5 GB.
Not impressed? It was made in _1982_. On a 286 speed equivalent machine. It took five days to render. And it was stunningly beautiful. Just (aside from you guys who actually _know_) imagine what they're doing now.

Yet another hubble story. Hmmm. I'm astonished by the amount of people who are ignorant of the purpose of the telescope. Yeah, sure, everyone looks at the pretty pictures and says "yay! space is fun!" or "we can learn sooooo much!!!" without ever taking a peek at the real picture.
This is sad and ironic given that looking to space is supposed to focus our perspective on earth. Sigh.
But even this is not the true mission of the Hubble Space Telescope. I work for one of NASA's Hubble teams, so I am privy to certain documents that aren't released to the public. Ordinarily I'd withhold this information, but I think it's time for certain facts to come to light. Many people discounted the telescope due to the gyroscope failure, but failed to understand the gravity of the situation (pun intended . . . I work for the government, remember?).
The Hubble Space Telescope exists to find signs of cheese in other celestial bodies, be they star system or stars themselves. The grand lunar cheese expeditions were a phenominal disaster due to the total lack of cheese on the moon, as had been previously believed. Subsequent missions were sent after the initial to see if maybe they were just looking in the wrong place.
We've found that they WERE. The Mars lander was covered up because no cheese was found there either (which we knew, but it never hurts to double check).
The way the Hubble works is by looking at major cheese centers on earth, and analyzing the various waves emitted by cheese (dubbed "dairyons"), and then points out towards space to see if it can match with any dairyon centers in space, so we know which direction to fire the next probes. It is believed that in 15 years we will have a vessel capable of retreiving any cheese we can locate now.
NASA has come under alot of flack lately for various "failures". Yet we long ago forsaw the imminent cheese-shortage that Earth will face within the next 7-10 years. We've been doing all we can to locate external cheese supplies to harvest. I hope you all understand and do what you can to support projects like the Hubble, even if you are doing it just to look at the pretty pictures.

I run BigCheese.com, soon to be the Internet's only vertical cheese portal (currently in development). Regardless of what the fine people at NASA are doing, it is completely false that the Earth faces any sort of cheese shortage in the near future. The cheese industry here on Earth is, right now, stronger than it has been at any point in the past. This is why BigCheese.com will soon provide the Internet's largest array of cheese-related content and services, from cheese-making resources to customized E-Cheese(tm) business-to-business supply chain solutions.
Far from there being an imminent shortage of cheese, the dairy industry is getting to be very crowded and competitive. To be effective in this market, your company will need to leverage the growing power of the Internet to create, market, distribute, and sell its products to a large number of buyers at a competitive price.
If they do find cheese on Mars, though, we could certainly provide a competitive cheese shipping solution to the Martian dairy farmers.:)

I really hope you're kidding. For my money, the Hubble is one of the best scientific investments we've _ever_ made -- it's absolutely unreal how much it has furthered astronomy and astrophysics in the years since it went up. The pretty pictures are great, sure -- they are beautiful, and beauty is I think something that any civilization discounts at its own peril. But there has also been a lot of pretty hard-core science from the Hubble -- witness the HST Key Project, which used the Hubble to observe remote Cepheids and calibrate the astronomical distance scale. Knowing the distance to all the objects in our Universe (and hence how old the light we're seeing is, how old our Universe is, etc.) is a pretty big deal, don't you think? The Hubble has also let us see, in far more detail than was possible before, the process of star formation itself -- think of the Eagle Nebula pictures, the so-called "pillars of creation." It's cool stuff.
Sorry if I'm ranting a bit here. My point is just this: if you want to rave about waste in our government, there are plenty of other places to look. Sure, the Hubble has had problems. Some of them have been stupid problems. But at maybe 6 billion dollars spent so far (the initial expenditure was quite a bit bigger than you quote, but I believe the shuttle flights cost less), it's been a bargain. And yes, I mean that seriously.:-)

Correction: One mission to fix the Hubble; two missions to upgrade it.
The Hubble was designed from the very beginning, in the early 70s, to be upgraded and serviced by the shuttle. While it was extremely unfortunate that the mirror flaw was not detected before it was on orbit, Hubble was able to do useful science even then; and after the fix it's performed superbly.
The gyros were expected to wear out, just maybe not so fast. The only real problem that's resulted was a bit of downtime, since the shuttle fleet was grounded for safety reasons last year (representing excellent quality control on the part of the shuttle teams); that wasn't Hubble's fault, though, and it went into safe mode as designed.
Estimating shuttle costs is an art, not a science, depending on how you include extraneous costs. Most people call a shuttle mission budget about HALF a $billion. Probably this is 5 to 10 times the cost that was expected during the Hubble design phase, but we're also flying the shuttle much less than expected -- which has nothing to do with Hubble.
I have no love for NASA; read _The Hubble Wars_ and you'll understand how the policitians and engineers took places in line before the scientists on this project far too many times. But in the end it's been a (qualified) success in so many ways.
In short, Hubble wasn't any more "broken" than your car is when you take it to Midas for new brake shoes. ----

FYI, that's not really true. The mirror wasn't warped, but just shaped wrong. At the time the mirror was made (not sure if it's still true), it was the MOST ACCURATE mirror ever designed. The problem was it was designed to the wrong standards. The testing apparatus to fine-tune the mirror's surface were incorrectly positioned from the mirror, so it was tuned VERY accurately to the wrong shape. It was the precise knowledge of the miscalculations which allowed the mirror to be fixed relatively easily.

When your fuel pump fails and your car doesn't start do you call the mechanic and say "I need my car fixed", or do you say "I need my car upgraded".
late reply, but maybe you'll see this in your log.
I said there was one mission to fix Hubble. You are correct, the first mission was an unplanned one to correct the optics. That was the mission I referred to.
As I stated, while it was unfortunate that the main mirror was imperfect, it was still able to perform good science: this is something that is made clear by Eric Chaisson, who was the Science Director of the Space Telescope Science Institute at the time.
As for the gyro replacement, this was a planned refit that was known to be necessary for many months. Shuttle scheduling pushed the original maintenance mission back many months, and when the Hubble ran out of working gyros, the shuttle was rescheduled as soon as possible to replace them.
Call it whatever you like; my point stands. The most recent Hubble servicing mission was already planned and expected. The fact that Hubble shut down and waited for the mission is irrelevant.
When you are due a 3000 mile oil change, and the oil change place is closed, and you stop driving your car until you can take it in for the oil change -- is that a "fix"? That's close to what happened here. ----

The issue with the hubble space telescope was the diffractive index of the multiple lenses. Unfortunately, some over zealous engineer forgot to take into account the relative pressure differences that would exist in space. Fortunately, the pressure miscalculation was not major problem but it did create a slight bulge or abberehation of the main lense of the hubble.

Hey great so nasa has this big telescope up in space and it can see numerous things which we on earth cant see (obvious reasons).
As has been with the case for the history of telescopes on earth, old and outdated telescopes have been replaced by new ones. If nasa was at all serious about the using telescopes in outer space we would have heard of plans of them building a new telescope.
The only reason i see them for maintaining hubble is because it provides nice public relations (we get to nice pretty pictures: which religious scholars get to call god..)
I mean cammme onnnn an news about hubble is old news.. We need to go the next step

Well while you're at it, why don't you whine about the Shuttle being 'old news' or the entire concept of communication sattelites?
Just because it's not Really New and Really Costly doesn't mean it's not good.

There are several bigger telescopes on the drawing boards - I remember reading about plans for an array of telescopes out in deep space that would have the ability to resolve landmasses on an Earth-size planet 10 lightyears away - cool or what?:)
I got a new catalytic converter for my truck today. Neighbors of mine, Mr. and Mrs. Loudbody, were quoted as saying, "That thing made the most god awful sound you could imagine. And he drove around at the oddest hours, too, sometimes waking us as early as 8pm, after we had the early bird special at Denny's. That puts ya to sleep real quick, ya know."
The late 199th decade vehicle is now known to be purring like a cuddly kitten. Once again able to reach speeds of 60mph in as little as three minutes. "There ain't nothin sweeter than cruising down the street at 30 when the speed limit is posted as 25," I was heard braggin at the local BigK.
NHK, the Japanese broadcasting agency had a special on what Hubble has discovered accompanied by the most moving and haunting soundtrack. They take this picture then seamlessly transition to a 3-dimensional CG flight through all the galaxies giving you an even greater impression of the depth. There has been many American and UK-made specials like this, even in IMax (Cosmic Voyage) but absolutely NOTHING compares to this. Has me reaching for the hankies everytime.

The hubble REPAIR mission cost more than the last 3 mars missions combined. If you want to start placing blame, talk to your congressman about NASAs dwindling budget.
NASA cant screw the hubble up. especially after its working right in the first place.
Too bad the people that fixed Hubble aren't the same one's in charge of the Mars Missions. It would be really nice for one of them to work.
I like the way they chose 'photogenic' objects to photograph (good PR, I guess). Maybe it's time to have a slashdot poll on the most photogenic stellar objects? My vote: Uranus
There are some higher resolution images on NASA's website.
Does anyone know of someplace that sells Hubble images? Some of the images would make great art.
Why is this stuff always reported on BBC but ignored by the American media? It's our fscking satellite. Still, this means the NASA mailing list will start getting interesting again...

"Thanks to the great work by the astronauts, Hubble is better than new,"
Not only did they correct the gyro problems which made pointing a little difficult, the continued efforts on correcting the optics making them better than ever.
"After a two-month hiatus, it is a tremendous boost to all of astronomy to see Hubble back in action. Nasa has restored the observatory to a condition that was better than it was even before the fourth gyroscope failed."
Hats off to NASA!
Never knock on Death's door:
More race stuff in one place,

This is good stuff, finally getting the 'scope up and running properly.
But its still passive observance. Not that I actually understand any of this, but wouldn't it be a good idea to spend some research dollars on a more active observation system? Impossible at today's tech level, but maybe not someday.
I guess I just want more pretty pictures.

The only reason the Martians have not shot down Hubble yet is because the highly reflective coating has been able to deflect the deathrays up until now. the last pit crew noted that the skin had "bubbled". this was due to multiple death ray shots, but NASA is covering it up
BTW, I am really SICK of being the only one outside of the conspiracy to be able to connect the dots
Bigger and better (well, mostly bigger) versions of the images can be found here and here
... I sometimes think the Hubble folks are trying to pull a fast one on us with these pictures :)
I always love pictures from Hubble; they are always stunningly beautiful. However, they tend to look almost *too* good, as if some graphics artist had a bit to much free time while fiddling about with The GIMP
Yet another hubble story. Hmmm. I'm astonished by the amount of people who are ignorant of the purpose of the telescope. Yeah, sure, everyone looks at the pretty pictures and says "yay! space is fun!" or "we can learn sooooo much!!!" without ever taking a peek at the real picture.
This is sad and ironic given that looking to space is supposed to focus our perspective on earth. Sigh.
But even this is not the true mission of the Hubble Space Telescope. I work for one of NASA's Hubble teams, so I am privy to certain documents that aren't released to the public. Ordinarily I'd withhold this information, but I think it's time for certain facts to come to light. Many people discounted the telescope due to the gyroscope failure, but failed to understand the gravity of the situation (pun intended . . . I work for the government, remember?).
The Hubble Space Telescope exists to find signs of cheese in other celestial bodies, be they star system or stars themselves. The grand lunar cheese expeditions were a phenominal disaster due to the total lack of cheese on the moon, as had been previously believed. Subsequent missions were sent after the initial to see if maybe they were just looking in the wrong place.
We've found that they WERE. The Mars lander was covered up because no cheese was found there either (which we knew, but it never hurts to double check).
The way the Hubble works is by looking at major cheese centers on earth, and analyzing the various waves emitted by cheese (dubbed "dairyons"), and then points out towards space to see if it can match with any dairyon centers in space, so we know which direction to fire the next probes. It is believed that in 15 years we will have a vessel capable of retreiving any cheese we can locate now.
NASA has come under alot of flack lately for various "failures". Yet we long ago forsaw the imminent cheese-shortage that Earth will face within the next 7-10 years. We've been doing all we can to locate external cheese supplies to harvest. I hope you all understand and do what you can to support projects like the Hubble, even if you are doing it just to look at the pretty pictures.
Forgive my sloppy prose. I'm a rocket scientist, not a writer.
What the hell is that supposed to mean? I don't get it.
Why is this stuff always reported on BBC but ignored by the American media? It's our fscking satellite. Still, this means the NASA mailing list will start getting interesting again...
There's no prurient interest, no shocking expose, no government waste, just plain old science, and too boring to bring in good ratings.

Well it must be to complicated to do fine adjustments in "buble buble"-space-suits. And they just found out they couldn't thrust the robots (Just found out from the tour d'Mars)
No the only reasonable must be that they uninstaled NT and installed Linux.. Then it became so much more clear and stabile
Who did the quality control for this thing? We have had 3 missions to fix the hubble since it went up. It costs roughly 1 billion every time the shuttle goes up. This is in addition to the innitial 1 billion or so. It has captured some stunning images, but between warped mirrors, bad solar panels, and failing gyros you would think this was put together by packard bell.
Here are the spots you can see the big images over at the Space Telescope Science Institute.
First, the Eskimo Nebula. And Abell 2218. Both sets of images are really really pretty.
For this and lots of other info from the Space Telescope Institute check out http://www.stsci.edu. It is an outstanding web site.

My Slashdot account is old enough to drink...
from the mike-killed-the-hubble-mike-killed-the-hubble dept.
What is that from? I know I didn't kill the hubble, honest...
Better use it well before it gets shot down
It takes about a year for missiles to travel from mars.
Though this is a troll, I will respond to it anyway. Since Slashdot has been bought out by Andover, one of the agreements was that the code Slashdot actually ran would be far superior to the code that was released. Why would they do that? One reason - since Slashdot has become more popular, many knock-offs have sprung up using the Slashdot code and basically having the same content. Andover wishes to keep these competitors small; they could not possibly grow anywhere near the same size Slashdot has without features such as moderation and karma - features the released code lacks. There, I hoped I cleared this up for everyone.
_sarcasm mode on_
Yeah - that's right. NASA's Mars guys must be stupid. Because designing budget priced hunks of steel and silicon that must be launched into orbit on tons of explosive fuel, then flung hundreds of thousands of miles through space, and finally come to land on a rocky planet with no atmosphere is easy.
_sarcasm mode off_
Sometimes things work, sometimes they don't - all NASA can do is make the best engineering effort they can to increase the probability of success.
Behold the power of cheese.
Personally, I don't care if it is moderated down, since it is horribly OT. But in case anyone feels like responding to it, please avoid flaming me or CmdrTaco and respond intelligently.
They say that Hubble is "better than new" now, but they don't explain in what way!
Does it take better pictures now, or will the better gyroscopes just make it last longer?
Such an act would only make Slashdot even more troll proof. I hope your threat is serious and that CmdrTaco is paying attention.
Just don't forget the crackers.
Oops, I should have proofread better. you probably know this, but it wasn't the mirror that was fixed during the first servicing mission, but another corrective lens was installed to fix the optical pathway.

So you cut the cheese. Better quit drinking those cheap beers, eh?
you are wrong. I don't know how you define fix, but the first mission undertaken was to install corrective optics because the thing couldn't see crap. I call that a mission to "fix" hubble. If something won't work until you replace a broken part, it needs to be fixed. As we all know Hubble was not working at all before it got new gyros. When your fuel pump fails and your car doesn't start do you call the mechanic and say "I need my car fixed", or do you say "I need my car upgraded".

That is All.
They need a better shielding system to deflect the death rays. Thus it REALLY IS NASA's fault for not protecting the Mars probes from Martian anti-spacecraft defenses.
They do not need to protect against projectiles since the Martians have no nitrates and never developed kenetic energy weapons of any power.
DUH!
This is one of the most worth while ventures that Humanity has undertaken. We have learn't more about Distant space in it's brief time in operation than in the entire time that the human race has been "watching the Stars".
The pictures that Huble has been providing has greatly interested me for years, and It excites me greatly to have at least another few years to get magnifisent pictures from the depths of space,
Well done this time NASA, for something that this time works properly (Dispite it's many glitches)

"your plastic pal thats fun to be with" sounds like a marketing ploy aimed at children ages 5 and up. perhaps something more... "hip" and "britney spears-ish" directed towards our budding adolescents would do the job. maybe... "I've got plastic in me, SO CAN YOU" would work

...a broken link. I guess I accidentally closed the 'href' with a colon instead of a quotation mark. Whatever.
My bad! That's funny, "They just pointed the telescope into empty space and they found..."
Just think of it though, all of those little blobs are galaxies! All of them!
Apparently this field covers an area roughly the same size as a dime held at arm's length. Think of how many dimes at arms length you would need to cover the sky. Then travel to the other side of the world and do it again. That's one hell of a lot of dimes. And a hell of a lot more galaxies.
All of a sudden I feel really small. I'm going to go silently rock back and forth in the corner now.
The issue with the hubble space telescope was the diffractive index of the multiple lenses. Unfortunately, some over zealous engineer forgot to take into account the relative pressure differences that would exist in space. Fortunately, the pressure miscalculation was not major problem but it did create a slight bulge or abberehation of the main lense of the hubble. New lenses were constructed to account for this and then subsequently replaced. Its not always easy to get it right the first time. That is why the multiple maintenance trips to fix the Hubble. New stabilizing gyros were added later on as an afterthought. Sure the Hubble was working "okay" but not up to par as had been envisioned when the project was first started. As you can see from the crisp clean pictures the Hubble has not only been fixed but improved as well. I say we give a NASA an overdue round of applause for sticking it out to the end.
