| Intergalactic 'wind' is stripping galaxies of star-forming gas Posted: 13 Nov 2014 12:29 PM PST Astronomers have provided the first direct evidence that an intergalactic 'wind' is stripping galaxies of star-forming gas as they fall into clusters of galaxies. The observations help explain why galaxies found in clusters are known to have relatively little gas and less star formation when compared to non-cluster or 'field' galaxies. |
| The party's over for these youthful compact galaxies Posted: 13 Nov 2014 11:00 AM PST Scientists have uncovered young, massive, compact galaxies whose raucous star-making parties are ending early. The firestorm of star birth has blasted out most of the remaining gaseous fuel needed to make future generations of stars. Now the party's over for these gas-starved galaxies, and they are on track to possibly becoming so-called "red and dead galaxies," composed only of aging stars. |
