| Galaxies in the early universe mature beyond their years Posted: 10 Mar 2014 06:39 PM PDT An international team of researchers has discovered the most distant examples of galaxies in the early universe that were already mature and massive. The mature galaxies were found at a record-breaking distance of 12 billion light years, seen when the universe was just 1.6 billion years old. Their existence at such an early time raises new questions about what forced them to grow up so quickly. |
| Possible evidence for dark matter particle presented at UCLA physics symposium Posted: 10 Mar 2014 06:23 PM PDT Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has so far eluded direct observation. At a recent UCLA symposium attended by 190 scientists from around the world, physicists presented several analyses that participants interpreted to imply the existence of a dark matter particle. The likely mass would be approximately 30 billion electron-volts, said the symposium's organizer. |
| 'Death stars' in Orion blast planets before they even form Posted: 10 Mar 2014 07:16 AM PDT Astronomers have studied the often deadly relationship between highly luminous O-type stars and nearby protostars in the Orion Nebula. Their data reveal that protostars within 0.1 light-years (about 600 billion miles) of an O-type star are doomed to have their cocoons of dust and gas stripped away in just a few millions years, much faster than planets are able to form. |
| Posted: 10 Mar 2014 06:06 AM PDT Australian astronomers have shown galaxies in the vast empty regions of the universe are actually aligned into delicate strings, according to new research. Using data from the Galaxy and Mass Assembly (GAMA) survey, the astronomers found that the small number of galaxies inside these voids are arranged in a new way never seen before. |
