The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight ...

For the first time, astronomers at MIT and elsewhere have watched as a supermassive black hole's own corona, the ultrabright, billion-degree ring of high-energy particles that encircles a black ...

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as ...

Despite the name, black holes often shine very bright in the sky, due to their hot glowing corona. Now, astronomers have been puzzled to watch a black hole’s corona suddenly vanish – and if ...

As that happened, the corona formed above the black hole. But the creation of the corona – a cloud of hot plasma – in this particular event surprised astronomers.

As the black hole, which sits at the heart of a galaxy located 250 million light-years away, feasted on the star's remains, scientists noticed a dramatic rise in high-energy X-ray light.These ...

Gas, dust and light that get sucked into a black hole are lost forever -- so it shouldn't be possible to see light from behind a black hole. But that's what astronomers saw in a galaxy about 800 ...

Black hole echoes are created by two types of X-ray light released from the corona, and astronomers can use the amount of time it takes for the telescope to detect the two types to track how a ...

Observations carried out by NASA's Swift and Nuclear Spectroscopic Telescope Array (NuSTAR) space telescopes may have located the source of intense X-ray bursts emitted by supermassive black holes.

Astronomers Spot Perplexing Sideways Black Hole; The second alternative is that 1ES’s corona is contracting, creating an oscillating pattern.

Is black hole at the centre of NGC 4395 a primordial relic? Afterwards, debris from the star would have knocked away material in the AGN’s inner accretion disk, causing much of it to suddenly fall ...
