![]() Moffett Field CA (SPX) Oct 14, 2010 Last month, astronomers announced the discovery of the first potentially habitable extrasolar planet. But this week at an International Astronomical Union meeting, doubts were raised about the existence of this exciting new planet said to be orbiting the star Gliese 581. Called 'Gliese 581 g,' the planet was determined to be about 3 times the mass of Earth, meaning it was a rocky world, not a gas giant like Jupiter. Rocky extrasolar planets have been found before, but the unique trait about this p ... read more |

Study Sheds New Light On How The Sun Affects The Earth's Climate![]() The Sun's activity has recently affected the Earth's atmosphere and climate in unexpected ways, according to a new study published in the journal Nature. The study, by researchers from Imperial College London and the University of Colorado, shows that a decline in the Sun's activity does not always mean that the Earth becomes cooler. It is well established that the Sun's activity waxes and ... more Ground-Based Images Of Asteroid Lutetia Complement Flyby ![]() On July 10, 2010, the European Space Agency (ESA) Rosetta spacecraft beamed back to Earth a dramatic set of close-up images as it flew past the 100-kilometer-sized asteroid (21) Lutetia, on its way to a comet rendezvous in 2014. But even before Rosetta made its close encounter with Lutetia, astronomers, using three of the world's largest telescopes, were busy making their own assessment of ... more NASA's WMAP Project Completes Satellite Operations ![]() After nine years of scanning the sky, the Wilkinson Microwave Anisotropy Probe (WMAP) space mission has concluded its observations of the cosmic microwave background, the oldest light in the universe. The spacecraft has not only given scientists their best look at this remnant glow, but also established the scientific model that describes the history and structure of the universe. "WMAP ha ... more |

![]() Boston MA (SPX) Oct 08, 2010 If you think global warming is bad, 11 billion years ago the entire universe underwent, well, universal warming. The consequence was that fierce blasts of radiation from voracious black holes stunted the growth of some small galaxies for a stretch of 500 million years. This is the conclusion of a team of astronomers who used the new capabilities of NASA's Hubble Space Telescope to probe the invisible, remote universe. Using the newly installed Cosmic Origins Spectrograph (COS) they have iden ... read more |
