Four billion years ago, Uranus and Neptune switched places during a gentle ride out to their current orbits. That's the conclusion of Steve Desch, an astrophysicist at Arizona State University, who thinks that all of the gas giant planets took shape twice as close to the sun as they are at present. His work could cut out much of the mystery of how our "impossible" solar system formed. picked by AutumnLotus 10 months ago tags trading cosmic places neptune uranus swapped |

In a bid to determine the melting temperature of ice in high atmospheric pressures, scientists have found a sharp increase in the melting curves, which opens up the possibility that water exists as a solid in the deep interior of planets such as Neptune, Uranus and Earth. picked by AutumnLotus 3 weeks ago 16 comments edit related share science |

Astronomers from SRON Netherlands Institute for Space Research have discovered a new cluster of galaxies, hidden behind a previously identified cluster of galaxies. The recently exposed cosmic giant is apparently just as bright as the first group, but is six times further away. The astronomers made the discovery as part of an international team using the space telescope XMM-Newton. picked by AutumnLotus 10 months ago 1 comments edit related share plime.com |

Astronomers said Wednesday that they had found a miniature version of our own solar system 5,000 light-years across the galaxy — the first planetary system that really looks like our own, with outer giant planets and room for smaller inner planets. 6 comments edit related share scienceThey also found signs of Elvis and Amelia Earhart. picked by mahler87 8 months ago |

ESA’s Integral has made the first unambiguous discovery of high-energy X-rays coming from a rare massive star at our cosmic doorstep, Eta Carinae. It is one of the most violent places in the galaxy, producing vast winds of electrically-charged particles colliding at speeds of thousands of kilometres per second. VIDEO included. picked by AutumnLotus 8 months ago 0 comments edit related share science |

Newfound glowing spots on Jupiter seem unexpectedly to come from electron beams whipping around the giant planet's volcanic moon Io. Io is the most volcanic body in the solar system, with its entire surface likely made up of lava from the moon's hundreds of volcanoes. picked by AutumnLotus 7 months ago 2 comments edit related share science |

Last September, a supernova burst into a cosmic flame 100 times more intense than any event on record—and left scientists scratching their heads. Now, two new studies attempt to explain the remarkable explosion. One sets up the explosion with a cannibalistic star, while the other describes how colliding layers of jettisoned gas could outshine all other supernovae. picked by AutumnLotus 11 months ago 0 comments edit related share plime.com |

The NASA/ESA Hubble Space Telescope has captured a new image of the galaxy NGC 1132 which is, most likely, a cosmic fossil – the aftermath of an enormous multi-galactic pile-up, where the carnage of collision after collision has built up a brilliant but fuzzy giant elliptical galaxy far outshining typical galaxies. picked by AutumnLotus 8 months ago 0 comments edit related share science |
