Most Distant Object in Universe Discovered by NASA? (Videos) *Object may be 13 billion year-old galaxy*


Object UDFj-39546284 (above - in lower right hand corner) may be 13 billion year-old galaxy

Most Distant Object in Universe Discovered by NASA?

NASA may have discovered the most distant object yet discovered in the Universe. The object, perhaps a galaxy, is estimated to be 13 billion light-years from Earth. The Universe is estimated to be 13.7 billion years old therefore the light from this "candidate galaxy" is from "shortly after" the Big Bang (700 million years later). Michio Kaku, in the second video below, notes that genesis, creation itself, lies beyond this galaxy as we look back in time 13 billion years ago. He also notes the shutter on the Hubble Space Telescope was left open for 100 hours to capture the light from this object.

NASA: The Universe's Most Distant Object This video is a zoom into the Hubble Space Telescope infrared Ultra Deep Field, first taken in 2009. It is a very small patch of sky in the southern constellation Fornax. The zoom centers on the farthest identified object in the field. The object, possibly a galaxy, looks red because its light has been stretched by the expansion of the universe. Credit: NASA/ESA/G. Bacon, STScI (no audio).

MSNBC: NASA May Have Found Oldest Galaxy Physics professor Michio Kaku explains what effect NASA's discovery of a galaxy that could be 13 billion years-old, almost as old as the Big Bang itself, could mean to science.
