Magnetars are a specific category of neutron stars that possess an unusually strong magnetic field. There aren’t many such celestial objects observed so far, although they could prove extremely interesting to scientists, since their powerful magnetism could have a strange impact on matter. Unfortunately, the mo... |

Black holes produce gravitational fields so powerful that they are able to shape space-time around them. However, what shape that particular volume of space surrounding the black hole might take under the influence of such an extreme gravitational field is unknown, as are the effects that might produce the powerful m... |

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... |

X-ray images of the Kes75 supernova remnant shows it to house what seems to be a rapidly spinning neutron star, commonly known as a pulsar, which could have been created in the outcome of the supernova explosion. Lying at a distance of about 20,000 light years away from Earth, Kes75's pulsar located close to the... |

An intense burst of gamma ray radiation, possibly coming from the Andromeda galaxy, has been detected in February last year, but, while trying to detect the gravitational wave produced by the event which triggered the radiation burst, scientists found there isn't one, thus ruling out the possibility of a mergin... |

From time to time, a huge explosion followed by a bright flash of light can be observed in space. It's a colossal gamma-ray burst (GRB), emitting for a few seconds as much radiation as a million galaxies.They are the most luminous events known in the universe since the Big Bang. They are flashes of gamma rays,... |

A magnetar is a neutron star with an extremely powerful magnetic field, the decay of which powers the emission of copious amounts of high-energy electromagnetic radiation, particularly X-rays and gamma-rays.Astronomers using data from several X-ray satellites have caught a recently discovered magnetar in a sort of g... |
