| How the universe's violent youth seeded cosmos with iron Posted: 30 Oct 2013 12:29 PM PDT By detecting an even distribution of iron throughout a massive galaxy cluster, astrophysicists can tell the 10-billion-year-old story of how exploding stars and black holes sowed the early cosmos with heavy elements. |
| Lava world baffles astronomers: Planet Kepler-78b 'shouldn't exist' Posted: 30 Oct 2013 11:29 AM PDT Kepler-78b is a planet that shouldn't exist. This scorching lava world circles its star every eight and a half hours at a distance of less than one million miles - one of the tightest known orbits. According to current theories of planet formation, it couldn't have formed so close to its star, nor could it have moved there. |
| Posted: 30 Oct 2013 11:28 AM PDT In August, researchers identified an exoplanet with an extremely brief orbital period: The team found that Kepler 78b, a small, intensely hot planet 400 light-years from Earth, circles its star in just 8.5 hours — lightning-quick, compared with our own planet's leisurely 365-day orbit. From starlight data gathered by the Kepler Space Telescope, the scientists also determined that the exoplanet is about 1.2 times Earth's size — making Kepler 78b one of the smallest exoplanets ever measured. |
| First results from LUX dark matter detector: Searching for elusive dark matter Posted: 30 Oct 2013 09:55 AM PDT In its first three months of operation, the Large Underground Xenon (LUX) experiment has proven itself to be the most sensitive dark matter detector in the world, scientists with the experiment have announced. Researchers are now preparing the detector, located a mile underground in an old South Dakota gold mine, for a 300-day run next year in hopes of detecting for the first time weakly interacting particles thought to account for most of the matter in the universe. Though dark matter has not yet been detected directly, scientists are fairly certain that it exists. |
