Hubblevolution

Stunning, isn't it? As a very heavy StumbleUpon user and lover of all things space, I stumbleupon pages containing this image quite often. And I never feel anything short of absolute awe. It's the Hubble Ultra Deep Field (I'm sure you already knew) and, in my opinion, it's the greatest image humans have ever produced.
A collection of snapshots of such a small patch of sky managed to capture about 10,000 galaxies. Such large implications from such small dimensions. And I don't mean to ignore all the other great images the Hubble Space Telescope has produced. I'm practically on my knees, grateful to this machine.
And now, there's this:

That's the James Webb Space Telescope, the significantly more technologically advanced successor of Hubble that's slated for a 2013 launch date. To NASA, it's a tool for studying the origins of the universe, the nature of galaxies and dark matter, and for analyzing planets for the potential of life. To all of us, it's another collection of high-resolution pixels to stir our imagination.
