Hot Gas on the Menu for Milky Way’s Black Hole

  ESA’s Herschel space observatory has made detailed observations of surprisingly hot molecular gas that may be orbiting or falling towards the supermassive black hole lurking at the center of our Milky Way galaxy. The environment at the centre of our Milky Way Galaxy. The Galactic Centre hosts a supermassive black hole in the region known as [continue reading]

VLA Finds Background Radio Emission is Submitted by Galaxies

  Staring at a small patch of sky for more than 50 hours with the ultra-sensitive  Karl G. Jansky Very Large Array (VLA), astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies. They found that about 63 percent of the background radio emission [continue reading]

Black Hole Wakes Up and has a Light Snack

  Astronomers have watched as a supermassive black hole woke up from a decades-long slumber to feed on a low-mass object – either a brown dwarf or a giant planet – that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the center of our own [continue reading]

Black Hole and Star Orbit Each Other at Dizzying Speed

  ESA’s XMM-Newton space telescope has helped to identify a star and a black hole that orbit each other at the dizzying rate of once every 2.4 hours, smashing the previous record by nearly an hour. Black hole-star pair orbiting at dizzying speed. Image Credit: ESA The black hole in this compact pairing, known as [continue reading]

Extremely Rare Triple Quasar Discovered

  For only the second time in history, a team of scientists including Michele Fumagalli from the Carnegie Institution for Science in the United States have discovered an extremely rare triple quasar system. Their work is published in the Oxford University Press journal Monthly Notices of the Royal Astronomical Society. An infrared image of the [continue reading]
