| Astronomer uncovers the hidden identity of an exoplanet Posted: 01 Jul 2013 01:39 PM PDT Hovering about 70 light-years from Earth –- that's "next door" by astronomical standards –– is a star astronomers call HD 97658, which is almost bright enough to see with the naked eye. But the real "star" is the planet HD 97658b, not much more than twice the Earth's diameter and a little less than eight times its mass. HD 97658b is a super-Earth, a class of planet for which there is no example in our home solar system. |
| Cloud behavior expands habitable zone of alien planets Posted: 01 Jul 2013 10:51 AM PDT A new study that calculates the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting red dwarfs, the most common type of stars in the universe. |
| NASA decommissions its galaxy hunter spacecraft Posted: 01 Jul 2013 08:06 AM PDT NASA has turned off its Galaxy Evolution Explorer (GALEX) after a decade of operations in which the venerable space telescope used its ultraviolet vision to study hundreds of millions of galaxies across 10 billion years of cosmic time. |
