Hubble uses gravity lense to find extremely distant galaxy
Washington DC (SPX) Oct 22, 2014
Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted a tiny, faint galaxy - one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away. This galaxy offers a peek back to the very early formative years of the universe and may just be the tip of the iceberg. "This galaxy is an example of what is suspected to be an abundant, underlying population of extremely small, faint objects that existed abou ... read more
