| Giant galaxy-packed filament revealed Posted: 17 May 2012 11:36 AM PDT Astronomers have discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament is the first structure of its kind spied in a critical era of cosmic buildup when colossal collections of galaxies called superclusters began to take shape. The glowing galactic bridge offers astronomers a unique opportunity to explore how galaxies evolve and merge to form superclusters.  |
| In chemical reactions, water adds speed without heat Posted: 17 May 2012 11:35 AM PDT Scientists have discovered how adding trace amounts of water can tremendously speed up chemical reactions -— such as hydrogenation and hydrogenolysis —- in which hydrogen is one of the reactants, or starting materials.  |
| Three-telescope interferometry allows astrophysicists to observe how black holes are fueled Posted: 16 May 2012 11:01 AM PDT By combining the light of three powerful infrared telescopes, scientists have observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, a method that has yielded an unprecedented amount of data for such observations. The resolution at which they were able to observe this highly luminescent active galactic nucleus has given them direct confirmation of how mass accretes onto black holes in centers of galaxies.  |
