Distant Black Hole Spin Measured by Astronomers

Astronomers this week revealed that the spin of a very distant black hole has been directly measured. The new measurement is part of a new report published this week in the journal Nature and should help cosmologists further investigate the characteristics and evolution of black holes. The spin of black hole/quasar RX J1131-1231 was measured by University of Michigan astronomer …

Stephen Hawking: Event Horizon Likely Doesn’t Exist

Respected physicist Stephen Hawking has just dropped a major bombshell: There may be no such thing as black holes as we know them. This belief would be eagerly dismissed should it have come from anyone else, but when Hawking speaks out on the matter, it may open the door to a serious debate. Where does Hawking’s belief come from? In …

Astronomers May Have Spotted a Double Black Hole

Astronomers this week revealed that a double black hole system may have been found. An object known as WISE J233237.05-505643.5 was spotted at the center of a galaxy 3.8 billion light-years from our solar system. The jet shooting up out of the supermassive black hole at the center of the galaxy appears to be wavy, rather than straight. This suggests …

NASA’s NuSTAR Finds Its First 10 Supermassive Black Holes

Astronomers this week announced that NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted its first 10 supermassive black holes. NuSTAR, an X-ray space telescope, was launched in June 2012 on a mission to conduct surveys for supermassive black holes (those billions of times more massive than our sun) and supernova remnants. A new paper, published in the Astrophysical Journal, describes …

Young Black Hole May Have Been Formed in Rare Supernova

Astronomers have found evidence that suggests the youngest black hole in the Milky Way galaxy may reside in the remnants of a rare supernova. The remnant, named W49B, is only around 1,000 years old and only 26,000 light-years from Earth. Astronomers have called the object “rare” because of the way the supernova took place. Instead of explosively ejecting matter in …

Radio-Emitting Jet Detected From Andromeda Black Hole

Astronomers revealed this week that they have detected an intense radio emission from a black hole’s radio-emitting jet. The emission was moving at more than 85% the speed of light, though it was also “quite variable.” The observations, published this week in the journal Nature, are the first detection of radio-emitting jets from a stellar-mass black hole outside the Milky …

Astronomers Spot the Most Massive Black Hole Yet Seen

Astronomers have measured the mass of what could be the most massive black hole yet discovered. The object, located at the center of the galaxy NGC 1277, is the equivalent of 17 billion Suns and makes up 14% of it’s galaxy’s mass. A paper on the black hole was published today in the journal Nature. NGC1277 is only 10% of …

Astronomers Spot the Most Massive Quasar Outflow Yet Seen

Astronomers have discovered a quasar with the most massive outflow ever seen. Quasars are bright galactic centers powered by supermassive black holes, and many of them accelerate the material around them, throwing it out a high speed in a process that plays a key role in the evolution of galaxies. The newly discovered quasar is, according to researchers, five times …

NASA Spots Milky Way Black Hole “Flare-Up”

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has taken its first images of the giant black hole at the center of our galaxy and caught it in the middle of a “flare-up.” “We got lucky to have captured an outburst from the black hole during our observing campaign,” said Fiona Harrison, the mission’s principal investigator at the California Institute of Technology. …
