SN 2008D, a supernova explosion detected by NASA's Swift X-ray Space Telescope inside the galaxy NGC 2770 on January 9, 2009, might have actually been triggered by the gravitational collapse of a massive star into a black hole, say researchers from the Max Planck Institute for Astrophysics, who claim that the ev... |

Gamma-ray bursts are the brightest and most powerful type of electromagnetic radiation that can be emitted in the universe in the outcome of a violent stellar explosion, whose afterglow remains extremely bright up to several hours after the occurrence of the event that generated it. A new study found that afterglows ... |

By making observations on a binary system of pulsars a team of researchers from the McGill University in Montreal measured for the first time the spin precession of a celestial body located outside the solar system. Pulsars are a type of neutron stars with strong magnetic fields, emitting electromagnetic radiation th... |

Supergiant high-mass X-ray binaries, HMXB for short, are stellar systems consisting of a supergiant star and a neutron star orbiting around it. HMXBs are relatively rare in the universe and are believed to be only a short phase in the life of binary star systems. At the time when ESA's gamma-ray space observator... |

Similar to neutron stars, quark stars are believed to be highly compact stellar objects that have been created during the supernova explosion of a relatively massive star. Theoretically, these objects may exist and could be formed only of elementary sub-atomic particles known as quarks, although none has been observe... |

The Crab Nebula, housing the Crab Pulsar at its center, is a supernova remnant of a stellar explosion that took place somewhere around 1054. It is located in the Taurus constellation about 6,500 light years away and at the time of the explosion it was allegedly visible on the sky in midday for as much as three weeks,... |

In 2005 and 2007, NASA Spitzer Space Telescope detected two narrow infrared signatures near the magnetar dubbed SGR 1900 14, suggesting that the star was surrounded by a ring of matter that remained in its vicinity after the progenitor star went 'nova'. SGR 1900 14 is a neutron star with a magnetic field a ... |

The star was in fact known for a long time to be a magnetar, albeit SRON Netherlands Institute for Space Research astronomers have only recently discovered that it emits a strange high energy X-ray beam, sweeping across the surrounding medium as the star revolves around its axis. "I was looking for new sources of hig... |

Pulsars are a type of rapidly rotating neutron stars with powerful magnetic fields, capable of projecting a beam of electromagnetic radiation that sweeps the surrounding space as they rotate. They are usually found in the company of white dwarf stars, although the latest addition to the long list of pulsars seems to ... |

Previously, astronomers believed that only black holes are capable to emit powerful X-ray jets, but a new study conducted at the Penn State University shows that, in fact, any class of object may be able to some extent to form powerful X-ray jets. A newly discovered neutron star seems to present features relatively s... |

The universe is practically littered with corpses of dead stars, or at least the visible part of the universe is. In fact, most of the matter forming the Earth comes from the bodies of one or more stars that shed part of their material at the end of their lives. However, not all the stars come to share the same fate.... |

GRB's, or gamma-ray bursts, are the most powerful radiation emissions released during cosmic collisions between massive objects such as neutron stars or possibly black holes. Most of the gamma-ray bursts received from the interstellar medium usually present long period bursts, which are thought to be produced b... |

White dwarfs are believed to be the remnant of a stellar core, after a supernova explosion, which would slowly cool and evaporate as time goes by, but this theory might be soon scrapped as observations made with the Suzaku X-ray space telescope reveals a new type of white dwarf presenting some strange features that h... |

Once believed to be a type of black holes, neutron stars usually form during the late stages of a star's life. They have masses ranging from 1.4 to 2.1 times that of the Sun and compact the matter in a volume from 20 to 40 kilometers in diameter, causing all matter that falls on their surface to disintegrate int... |

The object in question is a neutron star, known as RX J0822-4300, in close proximity to the center of the Milky Way, traveling at about 4.8 million kilometers per hour, and is thought to have been accelerated by the gravitational interaction with the supermassive black hole, present in the core of the galaxy, that mi... |
