The black hole is often referred to as Sgr A*, pronounced sadge ay star. Its mass is about 4 million times that of the sun, and it's about 27,000 light years from Earth, according to MIT.

Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with ...

The type of black hole that’s sitting in the center of a galaxy is different. This is a supermassive black hole, or SMBH, and — as its name implies — it’s much heftier.

Stock illustration of a black hole. According to black-hole expert Becky Smethurst, there could even be one lurking in the outskirts of our solar system.

Picture a black hole so powerful that it swallows the equivalent of one sun every day. Now imagine that black hole also has a mass that's 17 billion times larger than our sun. Scientists in ...

The giant black hole has a mass of 30 billion suns and sits at the center of a galaxy located hundreds of millions of light-years from Earth. Astronomers call the cosmic monster an ultramassive ...
