| Supermassive black hole blows molecular gas out of a galaxy at one million kilometers per hour Posted: 07 Jul 2014 09:14 AM PDT New research has solved a long-standing mystery surrounding the evolution of galaxies, deepening our understanding of the future of the Milky Way. The supermassive black holes in the cores of some galaxies drive massive outflows of molecular hydrogen gas. As a result, most of the cold gas is expelled from the galaxies. Since cold gas is required to form new stars, this directly affects the galaxies' evolution. |
| Small, but plentiful: How the faintest galaxies illuminated the early universe Posted: 07 Jul 2014 06:24 AM PDT Astronomers investigating the behavior of the universe shortly after the Big Bang have made a surprising discovery: the properties of the early universe are determined by the smallest galaxies. |
| Athena Observatory helping solve mysteries of the universe Posted: 07 Jul 2014 06:24 AM PDT The European Space Agency (ESA) has selected the Athena X-ray Observatory as its second 'Large-class' science mission in the 21st Century, which will help answer vital questions about the universe. |
