| Nearby failed stars may harbor planet, astronomers find Posted: 16 Dec 2013 11:28 AM PST Astronomers took precise measurements of the closest pair of failed stars to the Sun, which suggest that the system harbors a third, planetary-mass object. |
| Smithsonian's Submillimeter Array reveals giant star cluster in the making Posted: 16 Dec 2013 11:24 AM PST W49A might be one of the best-kept secrets in our galaxy. This star-forming region shines 100 times brighter than the Orion nebula, but is so obscured by dust that very little visible or infrared light escapes. Astronomers have peered through the dusty fog to provide the first clear view of this stellar nursery. |
| Innovative instrument probes close binary stars, may soon image exoplanets Posted: 16 Dec 2013 11:24 AM PST Close binary stars cannot be resolved with today's optical telescopes, despite adaptive optics that removes the fuzziness caused by atmospheric turbulence. An international team of astronomers has built and mounted on a 3-meter California telescope a fibered optic imager that combines AO and interferometry to resolve for the first time close binaries such as Capella, and have mounted an improved imager on an 8-meter Subaru telescope that may one day resolve planets around dwarf stars. |
