A new set of computer simulations has revealed that the solar system may have contained an additional planet when it first developed, an object that was extremely massive by the look of things. The space body must have been ejected a long time ago, the team adds. Certain interpretations of the new model even indicate... |

Astronomers were recently able to determine that a day on the gas giant Neptune lasts for 15 hours, 57 minutes and 59 seconds. Scientists have been trying to figure this out for many years, but thus far their studies have been stifled by lack of accurate data.
In order to arrive at the new conclusions, a group of... |

Pluto was once a fully-fledged planet, considered by astronomers to be the ninth such object from the Sun. However, following a length and very divisive discussion in the international scientific community, the celestial body was demoted to a dwarf planet back in 2006. Since then, many experts have been arguing about... |

The conclusions of a new scientific study provide the first evidence that microbes can indeed survive being blasted into space, traveling for millions of years, reentering an atmosphere, and then making their way to the surface of an alien body. Until now, experts have hypothesized that this is possible, but investig... |

In January 2005, astronomers peering into the night sky made an impressive find, a new celestial body which its discoverer first called Xena. Over the years, the finding proved critical, as it led to the creation of the dwarf planet category, and the demotion of Pluto from full-blown planet. Earlier this month, it wa... |
