Telescope Finds Pubescent Galaxies

This NASA photo is a composite image from a number of telescopes, including NASA's Hubble Space Telescope, which shows a space blob in both optical and infrared light. The blob is the yellow mass of gas. Inside it is an adolescent galaxy in white. The red spots are galaxies seen in the infrared spectrum.

A new study using NASA’s Chandra X-Ray Observatory and other telescopes explains the high-energy glowing blobs that astronomers have observed for a decade.  Once thought to be infant galaxies, the new study found they were actually pubescent galaxies.  These blobs are extremely active with gas halos and growing black holes.  According to co-author Bret Lehmer this stage is necessary so that the galaxies do not become too large. For more information on this study, see the Chandra X-Ray Observatory’s website.
