ASTRONOMY:
Seeing the Universe's Red Dawn
Ann Finkbeiner
Astronomers have found what may be the farthest and oldest galaxies ever seen. So distant that the expansion of the universe has stretched their ultraviolet light all the way into the infrared region of the spectrum, they may have formed just a few hundred million years after the universe itself. It took a 36-hour exposure with an infrared camera on the Hubble Space Telescope to see them.
