The Deepest Photo Ever Taken

Posted by timothy on from the whoah-dude-that's-deeeeep dept.

Astroturtle writes "Astronomers using the Hubble Space Telescope's powerful new Advanced Camera for Surveys (ACS) have taken the deepest visible-light image ever made of the sky. The 3.5-day (84-hour) exposure captures stars as faint as 31st magnitude, according to Tom M. Brown (Space Telescope Science Institute), who headed the eight-person team that took the picture."

    ...and it is, hubble has some type of cryogenic cooler onboard. At least according to an article in Sky and Space magazine (it's an australian one AFAIK) a while back that talked about all the extra stuff that was put on hubble last time a shuttle stopped by to maintain it.

    The grandeur of such an image almost forces one to reasses their place in the world. To think that the area in the photograph is equivalent to the area covered by a grain of sand at arms length is mindnumbing. The universe is unbelieveably amazing.
