Black Hole

Astronomers have detected a gravitational wave signal that appears to have been caused by a black hole swallowing a neutron star. Aside from being an incredible cosmic cataclysm to witness, this detection is important for another reason: it may be the final p…

Trying to find events out in space is tedious because you wouldn't know if what you've found is the actual thing or if it's just noise. But on August 14, astronomers might have picked up a possible collision between a black hole and a neutron star which would…

A supermassive black hole sits at the center of our galaxy and there are usually no activities being detected from it, until astronomers notice the black hole called Sagittarius A* lighting up brighter than normal in May. The closest supermassive black hole …

The supermassive black hole at the center of the Milky Way is normally quiet, but in May it surprised astronomers with an unprecedented explosion of infrared light. The closest supermassive black hole to Earth, called Sagittarius A* or Sgr A*, suddenly got…

You don’t usually think of a supermassive black hole as something that can go unnoticed, but many of these interstellar monsters are quite placid. For instance, Sagittarius A* (pronounced “Sagittarius A Star”) in the center of our own Milky Way galaxy. It’s u…

What made the black hole turn bright so suddenly? (Getty) The supermassive black hole at the heart of our galaxy suddenly glowed far, far brighter than normal - becoming 75 times more luminescent - before going back to normal. Scientists are trying to figur…

The supermassive black hole at the center of our galaxy has become unexpectedly active, with astronomers generally puzzled as to why Sagittarius A* has suddenly lit up with extreme brightness. Almost 26,000 light years from Earth, Sagittarius A* – or Sgr A* –…
