Powerful Galaxies Found in Infrared

Posted by Zonk on from the larger-galaxies-could-mean-billions-of-denny's dept.

demachina writes "NASA's Spitzer Infrared space telescope has discovered 'a mysterious population of distant and enormously powerful galaxies radiating in the infrared spectrum with many hundreds of times more power than our Milky Way galaxy.' They are 80% of the way back to the big bang. They found them by comparing a visible and infrared scan of the sky and looking at the places where there was a big infrared signature and no visible one. They are shrouded in dust."

    This is a great example of why ground based telescopes cannot be a substitute for space based ones.
