LA, those are some incredible photos, which makes me wonder if the Hubble telescope is the most impressive piece of technology that has come around in my lifetime. I can't think of anything else as impressive.

The very, very dim galaxy in this photo is called UDFj-39546284 and is the most distant galaxy ever seen. According to the folks at NASA, the light from that galaxy traveled for 13.2 billion years before it reached Hubble. (The estimated age of the universe is 13.7 billion years.) It's a small galaxy, approximately 1/100th the size of the Milky Way.

This is fun to contemplate:
There is a lot of ice frozen into the Martian crust. The heat of an enormous impact would melt a huge amount of it. If, as some believe, there are microbes living deep under the Martian surface, such a burst of warm, wet conditions over a substantial chunk of the planet would give them a brief chance to thrive at and close to the surface before the planet refroze. It’s not obvious how to observe such exciting developments, but there are surely already people at NASA and elsewhere giving thought to the matter. And they will have time. Parts of the surface and subsurface in the impact region, if there is an impact, will stay warm for decades.

Stupid questions here:Originally Posted by LA Ute
Wouldn't the heat and pressure from such an impact vaporize a lot of the water? Would other materials be transformed into a gaseous state? If so, would Mars at least transiently have an atmosphere and maybe take quite a while to cool off and return back to its current state? Like I said, pretty stupid questions.
Not stupid. It's fun to wonder about such things.
That would have been one heck of a fireworks show if it could be compressed by time-lapse.

How to View Five Planets Aligning in a Celestial Spectacle
19PLANET-superJumbo-v2.jpg
Five planets paraded across the dawn sky early Wednesday in a rare celestial spectacle set to repeat every morning until late next month.
Headlining the planetary performance are Mercury, Venus, Mars, Saturn and Jupiter. It is the first time in more than a decade that the fab five are simultaneously visible to the naked eye, according to Jason Kendall, who is on the board of the Amateur Astronomers Association of New York.

Well, because he thought it was good sport. Because some men aren't looking for anything logical, like money. They can't be bought, bullied, reasoned, or negotiated with. Some men just want to watch the world burn.
Watch your dirty, math mouth!
Wait until it turns out Dr Bob ate a greasy burger and it was just a spot of grease on the lens.
This is another perspective-expanding experience. Seriously, take 4 minutes and watch it.

I tend to agree. It's pretty incredible what they have done and the images they get. The coolest part is the in place repair to the mirrors they do.
All this makes me want to weep for the state of our space program right now.
Agreed about the state of our space program right now. The US has definitely lost it's superiority in that area.

Absolutely stunning images from Hubble. The fact it was almost the most impressive blunder of all time is equally impressive.
The only things I can think of that are as impressive as the Hubble Telescope would be the Kepler Telescope, out there finding all these new planetary bodies and trying to find the ones in the habitable zones (http://kepler.nasa.gov/), the Large Hadron Collider which has lead to the discovery of the Higgs-Boson, and the 2 Voyger missions which both are now outside our solar system (http://voyager.jpl.nasa.gov/)
I'll be sad when we stop getting images from Hubble.
Early galaxy formed stars at blistering pace
Scientists discover the earliest known starburst galaxy, which made stars more than 1,000 times faster than our Milky Way. They are surprised that a galaxy that early could make stars so rapidly.
Peering deep into the universe, scientists have discovered the earliest known starburst galaxy — a revved-up stellar factory popping out stars thousands of times faster than the Milky Way.
The find, described in Thursday's edition of the journal Nature, could help alter scientists' understanding of the early evolution of galaxies and larger structures in the universe.
The galaxy, named HFLS 3, existed about 880 million years after the big bang, when the universe was about 6% of its current age, astronomers say. And it's churning out stars with sun-sized mass at the incredible rate of roughly 2,900 per year.
A typical starburst galaxy may produce the equivalent of hundreds of suns per year, scientists said. The Milky Way, by comparison, creates about two suns annually....

That galaxy was obviously not a union shop.

NASA's planet-hunting telescope has discovered two planets that seem like ideal places for some sort of life to flourish. And they are just the right size and in just the right place.One is toasty, the other nippy.
The distant duo are the best candidates for habitable planets that astronomers have found so far, saidWilliam Borucki, the chief scientist for NASA's Kepler telescope. And it's got astronomers thinking that similar planets that are just about right for life — "Goldilocks planets" — might be common in the universe.
The planets are slightly wider than Earth, but not too big. Kepler-62-e is a bit balmy, like a Hawaiian world and Kepler-62-f is a bit frosty, more Alaskan, Borucki said.
The pair is 1,200 light-years away; a light-year is almost 6 trillion miles.
"This is the first one where I'm thinking 'Huh, Kepler-62-f really might have life on it'," said study co-author David Charbonneau of Harvard. "This is a very important barrier that's been crossed. Why wouldn't it have life?"
To make it warm enough for life the planet would need greenhouse gas trapping its star's heat because the star only gives off one-fifth the energy of our sun, but that's something that is likely to happen, Borucki said.
Both planets are tantalizing. The dozens of researchers who co-authored the study disagree on which one is better suited to life. Lisa Kaltenegger of the Max Planck Institute of Astronomy in Germany likes Kepler-62-e more because it's closer to the star and is warmer. She said it is probably "like Washington in May."
That planet is so close it may need clouds to cool off and it's more likely to be an all-water world, unlike any other in our solar system, Kaltenegger said. Astronomers cannot confirm that either planet has water, but based on other research, it's a good assumption, she said.
The planets circle a star that is 7 billion years old — about 2.5 billion years older than our sun. Kepler spots the planets as they go between Earth and their star ever so slightly, reducing the light from the star.
"If there's life at all on those planets, it must be very advanced" evolutionarily because the planets are so old, said Borucki.
On a watery planet, oceans are prime spots for life, including flying fish that could evolve into birds, Borucki said. And on the rocky planet, with a heavier gravity than Earth, life might look a tad different, he said.

Andromeda is the nearest spiral galaxy to the Milky Way. To put things in perspective, if the orbit of Neptune were the size of a $0.25 cent quarter, the nearest star (Proxima Centauri) would be 371.6 feet away, the nearest Black Hole (V4641 Sgr) would be 26.5 miles away, the Milky Way would be 1,200 miles across, and the nearest point of Andromeda would be 41,340 miles away.
