  Binary Star System D9 Found Orbiting Sagittarius A* Near Milky Way’s Core

  Astronomers have detected a young binary star system, D9, orbiting Sagittarius A*, the supermassive black hole at the Milky Way's centre. This challenges previous assumptions about star survival near intense gravitational forces. The discovery was made using the European Southern Observatory's Very Large Telescope. Future research with advanced tel...

  Supermassive Black Hole at the Centre of the Milky Way Is Spinning Unexpectedly

  Sagittarius A* (pronounced Sagittarius A Star), the supermassive black hole at the centre of the Milky Way, is spinning in an unusual way, and scientists now believe they may know why. Based on new data from the Event Horizon Telescope, researchers suggest that this cosmic giant likely merged with another black hole billions of years ago. This colo...

  Astronomers Spot Hot Gas Bubble Spinning Clockwise Around Milky Way Black Hole

  Astronomers said Thursday they have spotted a hot bubble of gas spinning clockwise around the black hole at the centre of our galaxy at "mind blowing" speeds. The detection of the bubble, which only survived for a few hours, is hoped to provide insight into how these invisible, insatiable, galactic monsters work.

  How The 1st Image Of The Supermassive Black Hole At Milky Way's Centre Was Captured

  Black holes are among the most profound predictions of Einstein's theory of general relativity. They were originally studied as a mere mathematical consequence of the theory rather than as physically relevant objects.

  How The EHT Super-Telescope Snapped The Supermassive Black Hole

  Powerful enough to spot a golf ball on the moon, the Event Horizon Telescope (EHT) is a network of radio dishes designed to detect the light cast when matter disappears into the maw of a black hole.

  First Pic Of Black Hole In Milky Way's Centre, 27,000 Light Years Away

  An international team of astronomers on Thursday unveiled the first image of a supermassive black hole at the centre of our own Milky Way galaxy -- a cosmic body known as Sagittarius A*.

  Black Hole Image of Sagittarius A* Unveiled by Scientists, From the Centre of the Milky Way Galaxy

  Scientists have provided the first look at the black hole — called Sagittarius A*, or SgrA — lurking at the centre of our Milky Way galaxy, unveiling an image of a supermassive black hole that devours any matter wandering within its gargantuan gravitational pull.

  Astronomers Piece Together First Image Of Black Hole

  After training a network of telescopes stretching from Hawaii to Antarctica to Spain at the heart of our galaxy for five nights running, astronomers said Wednesday they may have snapped the first-ever picture of a black hole.

• NASA discovers new black hole in Milky Way

  NASA's Swift satellite has found evidence of the presence of a previously unknown stellar-mass black hole in our Milky Way galaxy. Named Swift J1745-26 after the coordinates of its sky position, the nova is located a few degrees from the centre of our galaxy towards the constellation Sagittarius, NASA said.
