Is there a black hole in the Andromeda galaxy? Astronomers confirm intermediate-mass black hole in Andromeda galaxy. Astronomers at the University of Utah have confirmed an intermediate-mass black hole, an elusive rarity long sought by scientists. The object is hidden in...
Is there only one supermassive black hole? Supermassive black holes contain between one hundred thousand and ten billion times more mass than our Sun. As of 2022, there are over 150 confirmed supermassive black holes in our local Universe (with direct...
Is there a black hole in our solar system? The newly detected wandering black hole lies about 5,000 light-years away, in the Carina-Sagittarius spiral arm of our galaxy. However, its discovery allows astronomers to estimate that the nearest isolated stellar-mass black...
Does the Milky Way have 2 black holes? The Event Horizon Telescope (EHT) has now produced images of two supermassive black holes: the one in the center of a galaxy called M87 and the one at the center of our own...
Can black holes run out of space? Eventually, as the universe ages, the material around a black hole will run out and its doomsday clock will start ticking. As a black hole evaporates, it slowly shrinks and, as it loses mass,...
Are black holes real 2022? University of California – Berkeley. “Astronomers may have detected a ‘dark’ free-floating black hole: Gravitational microlensing turns up black hole candidate, one of 200 million in the galaxy.” ScienceDaily. ScienceDaily, 10 June 2022. How many black...
Where are black holes on Earth? Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas. This...
What is Cygnus X-1 and why is it significant? Cygnus X-1, binary star system that is a strong source of X-rays and that provided the first major evidence for the existence of black holes. Cygnus X-1 is located about 7,000 light-years...
Is a dark star possible? Scientists think that out of this rich environment, a new breed of star was born: dark stars. Dark stars are somewhat of a misnomer — they’re not actually dark. In fact, they’re likely some of the...
Is Cygnus X-1 in our galaxy? Cygnus X-1 is located inside the Milky Way about 7,200 light years from Earth. It comprises what we now know to be a black hole in a 5.6-day orbit around a massive supergiant companion star....
