Hubble Ultra Deep Field 2009
Astronomers took advantage of another new instrument, the Wide Field Camera 3 (WFC3), to peer just a bit farther into space. The resulting image was the deepest portrait of the universe ever taken in near-infrared light. Due to the expansion of the universe, the light from very distant galaxies is stretched and is best seen at infrared wavelengths. The faintest and reddest objects in the image are galaxies a few hundred million light-years beyond any that had ever been seen. The photo was taken over four days in August 2009.
