NASA Telescope Discovers Distant Galaxies
An infrared telescope powered by NASA has located a number of galaxies located more than 11 billion light years away from Earth.
The Spitzer Space Telescope, through the use of infrared, noticed galaxies that are being called the most luminous in the universe. According to ABC News, the newly found 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.
By studying these galaxies, we’ll get a better idea of our own galaxy’s history,” said lead author James Houck, also of Cornell.
The Spitzer infrared telescope, a $670 million mission launched in August 2003, is managed by NASA’s Jet Propulsion Laboratory in Pasadena.
