Astronomers Find A Binary Black Hole Inside Closest Quasar

August 30, 2015 |

Using NASA’ Hubble Telescope, a team of astrophysicists and astronomers has found in the core of the dwarf galaxy Markarian 231 (Mrk 231) — also known as UGC 8058 — a binary black holes orbiting furiously around each other. Read More

NASA Detects The Brighest Flare Ever From A Distant Galaxy

July 14, 2015 |

Astronomers have managed to analyse a spectacular flare from a supermassive black hole at the center of galaxy 3C 279, a record flare that happened five billion years ago. Read More

Astronomers Discover The Most Luminous Galaxy In The Cosmos

May 23, 2015 |

Far off in the universe, there’s a remote galaxy that shines as bright as 300 trillion suns and according to NASA, it is currently the most luminous galaxy ever seen. Read More

Hubble Spots Green Remnants Of Colliding Galaxies Near Dead Quasars

April 3, 2015 |

Quasars are known to be super-energetic and compact regions surrounding a supermassive black hole at the center of a galaxy. Quasars usually get their luminosity and electromagnetic energy from the nearby black holes that spew back tons of energy in various forms while they feed on the mass from their surroundings.

Scientists Find Monster Black Hole Dating to Cosmic Dawn

February 27, 2015 |

Quasars — supermassive black holes found at the centre of distant massive galaxies — are the most luminous beacons in the sky. These central supermassive black holes actively accrete the surrounding materials and release a huge amount of their gravitational energy. Read More

Astronomers Find a Distant Quasar with Strange Dimming Behavior

January 24, 2015 |

If a black hole is Voldemort, a quasar is Sauron; Despite being concentrated in an area no larger than our solar system, one, single quasar can outshine our galaxy by a factor of 100, generating more energy in moments than the Sun ever will. However, the mechanism by which they are powered is remarkably simple: at the heart of every quasar is a black hole that has been turbocharged. At least, that’s the working theory anyway. Read More

Amazing Facts About Quasars

December 4, 2014 |

Quasars or quasi-stellar radio sources are enigmatic objects in the far universe whose energy output outclasses several galaxies put together. These high-redshift objects are supposed to be powered by supermassive black holes. Read this article to know more about these mind-boggling active galactic nuclei objects, that have baffled astrophysicists for years. Read More

Astronomers Find Cluster of Quasars Aligned Perfectly Across Billion Light Years

November 22, 2014 |

Quasars are the most luminous objects in the universe, beacons that shine across vast cosmological distances. They are galaxies that have particularly active supermassive black holes at their cores, objects surrounded by discs of extremely hot matter spiralling into oblivion and emitting bright beams of particles along their spin axes at nearly the speed of light.
