CAPE CANAVERAL, FLORIDA, Sept 29: Piecing together 10 years of Hubble Space Telescope images, astronomers on Tuesday unveiled the deepest view yet of a small sliver of the night sky, revealing a kaleidoscope of galaxies and other celestial objects. The Hubble eXtreme Deep Field, or XDF, adds another 5,500 galaxies to Hubble’s 2003 and 2004 view into a tiny patch of the farthest universe. (agencies)
