Monster Elliptical Galaxy Sets Age Record --"Reveals Clues to Today's Dark-Matter Domination of the Universe"
Astronomers using NASA's Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. The galaxy existed 9.6 billion years ago and belongs to the galaxy cluster, IRC 0218. These "lensing" galaxies are so massive that their gravity bends, magnifies, and distorts light from objects behind it, a phenomenon called gravitational lensing. Finding one in such a small area of the sky is so rare that you would normally have to survey a region hundreds of times larger to find just one.
