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."

    in the constellation Bootes the Herdsman, the IRS team selected and observed 31 that are quite bright in the infrared but invisible in the NOAO survey.

    So you really can't hide from the IRS :(

    If these are really powerful galaxies then they will think the milky way is a girly sounding name and beat it up. I propose 'the hard as coffin nails' galaxy be adopted.

    I thought a galaxy had to be a collection of stars; which omit visible light?

    So? These ones are omitting visible light. :)
