@Lunar, and all: It is 11 days (total exposure time, I think it took longer to actually do it), right?

And yea, I was joking about the bad quality.   It's a wonder that they've pushed the telescope to the limit like that.  Wikipedia said it would take a million years or something to do the whole sky in that detail.

I didn't know that was the original purpose, but it makes sense given the name.  So they must have a lot of spectrometers on there to measure the redshifts?  I'm hoping I get to measure a redshift someday with a telescope - I see some catalogs sell adapters with diffraction gratings, so it must not be outside the amateur realm.

Truly spectacular!

Dude, those are simply amazing..... Very cool site you found..... Will be nice to one day get off this rock and go explore something really interesting.....

I actually wonder how long it really did take to expose those pics. Hmmm..... I never really considered that....

@CelticCurls, im under the impression that the images we are lucky enough to see are actually a by product, I believe Hubble was intended to measure the hubble constant (hubbles law) which basically describes the observations in physical cosmology and that the velocity at which various galaxies are receding from earth is proportional to their distance from us, or something along those lines, using red shift i believe?

Either way im happy to see whatever we we're shown, everytime i see just one image im blown away by the sheer size of the universe and it always begs the question, how big is the universe itself? matter is moving, but the space in which all is contained is another matter LL

@Gemmell. Yeah some images appear a little bland compared to others, but there are reasons for this. Hubble has returned so many fantastic images that there are enough for everyone to appreciate

The Ultra Deep field may not be as pretty, but it's amazing what it represents.  You gotta think too, maybe way back 13 billion years ago things weren't quite as beautiful.

And what awful signal-to-noise ratio - what's with this ISO 1600 stuff, eh?   It only took 11 days to expose, right?

Wonderful!  Thanks for posting them!

the orion nebula is cool the other on is a bit dull, makes you think though, is there something else out there or were we just one big fluke!
