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."

    How did they take this over 3.5 days? Didn't the sun get in the way? Last time I checked, only regions north of the arctic circle get no light for a few days, and that only occurs at specific times of year, so... what gives?
