NASA Telescope Spots Faraway Galaxies
NASA Infrared Telescope Spots Galaxies 11 Billion Light-Years Away, Scientists Report
LOS ANGELES Mar 2, 2005 — NASA scientists said an infrared telescope peered deep into stardust and spotted hidden galaxies more than 11 billion light-years from Earth.
In a journal article this week, the scientists describe how the Spitzer Space Telescope was used to find the galaxies, the most luminous in the universe. The galaxies shine with light equivalent to 10 trillion suns but are too far away and too drenched in cosmic dust to be seen until now.
"We are seeing galaxies that are essentially invisible," said Dan Weedman of Cornell University, in Ithaca, N.Y., who co-authored an article on the discovery in Astrophysical Journal Letters.
