Astronomers have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs were siblings orbiting each other. They slowly spiraled inward until they merged, touching off a titanic explosion. CfA observations show the strongest evidence yet of what was, until now, a purely theoretical mechanism for creating a supernova. picked by AutumnLotus 10 months ago tags white dwarf sibling rivalry explodes supernova sibling |

Through some of the very first scientific observations with the brand-new Large Binocular Telescope (LBT) in Arizona, astronomers has found that a recently discovered tiny companion galaxy to our Milky Way, named the Hercules Dwarf Galaxy, has truly exceptional properties: while basically all of its known peers in the realm of these tiny dwarf galaxies are rather round, this galaxy at a distance o... read full post picked by AutumnLotus 12 months ago 2 comments edit related share plime.com |
Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter. Mario Mateo and Matthew Walker measured the velocity of 6,804 stars in seven dwarf satellite galaxies of the Milky Way: Carina, Draco, Fornax, Leo I, Leo II, Sculptor and Sextans. They found that, contrary to what Newton's law of gravity predicts, stars in these galaxies do not move ... read full post picked by AutumnLotus 11 months ago 0 comments edit related share plime.com |

Two rocks found together in Antarctica are chunks of a dwarf planet that was smashed apart early in the solar system's history, detailed studies suggest. Other remnants of the proto-world may still be floating around in the asteroid belt, and might be identifiable by the spectrum of the sunlight they reflect. picked by AutumnLotus 6 months ago 2 comments edit related share science |

New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell a completely different story. picked by AutumnLotus 8 months ago 0 comments edit related share plime.com |

A mythical and ghostly creature has appeared in the wilds of the Scottish Highlands. A rare white stag, from the red deer species, is believed to be among just a tiny handful living in Britain, according to a conservation group. White stags are seen as a magical and powerful force in many mythologies and the John Muir Trust is now keeping the stag's location secret for fear of poachers. picked by AutumnLotus 7 months ago 9 comments edit related share science |

Jets of matter have been discovered around a very low mass 'failed star', mimicking a process seen in young stars. This suggests that these 'brown dwarfs' form in a similar manner to normal stars but also that outflows are driven out by objects as massive as hundreds of millions of solar masses down to Jupiter-sized objects. picked by AutumnLotus 1 year ago 0 comments edit related share plime.com |
