Behind CL1358+62: A New Farthest Object
What if we could see back to the beginning of the universe? At one tenth the universe's present age , we might see galaxies forming . But what did galaxies look like when they were forming? These questions took a step toward being answered yesterday with the release of analysis of a Hubble Space Telescope (HST) photograph of the most distant object yet discovered. Pictured in the box above, this galaxy appears to us - billions of years later and across the universe - as a faint red smudge. In technical terms, this galaxy lies at the record redshift of z=4.92. Practically all of the yellow-white objects in the photograph are galaxies in a nearby cluster which together act as a lens in amplifying the light from the ancient galaxy. A follow-up picture by the ground-based Keck Telescope actually measured the distant redshift.
