The Deepest Picture of the Universe Ever Taken: the Hubble Extreme Deep Field

Posted by Unknown on from the do-the-dew dept.

The Bad Astronomer writes "Astronomers have unveiled what may be the deepest image of the Universe ever created: the Hubble Extreme Deep Field, a 2 million second exposure that reveals galaxies over 13 billion light years away. The faintest galaxies in the images are at magnitude 31, or one-ten-billionth as bright as the faintest object your naked eye can detect. Some are seen as they were when they were only 500 million years old."

    They took many exposures totaling 23 days. From TFA:

    This image is the combined total of over 2000 separate images, and the total exposure is a whopping two million seconds, or 23 days!
