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... |

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,... |

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 ... |

It's not the first time - and probably not the last either - when your galaxy commits acts of cannibalism against its smaller companions orbiting around it. Researchers from the Research School of Astronomy at the Australian National University reveal that they have discovered debris of a possible encounter betw... |

The Geminga pulsar was created about 340,000 years ago through the supernova explosion of a regular star, inside what is now called the Geminga supernova. It is well known that supernovae can provide with the required energy to accelerate energetic elementary particles into interstellar space, the so-called cosmic ra... |

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... |

We used to think that Quasi Stellar Objects or quasars are the most energetic structures in the Universe, but this doesn't seem to be the case with the Milky Way, and why would our galaxy be more special than the others? The quasar is a special type of black hole, which goes through a 'feeding' process... |

Not only worms can be parasites. But stars, too. A pulsar (dead spinning star) has been discovered swallowing material from its companion star, dwindling it until the latter becomes an object smaller than many common planets."This object is merely the skeleton of a star. The pulsar has eaten away the star's oute... |

It is known that the Earth's molten metal core fuels a magnetic field. Now, a team has generated similar self-sustaining fields even when the flow is highly turbulent. The new approach is a closer simulation of the Earth's dynamo than other experiments as the fluid flows freely in a large tank and is not c... |
