Sagittarius A is located about 27,000 light years away from our solar system. It has an estimated mass of more than 4 million times that of the sun. It's about 24 million kilometers in diameter. The black hole is no...
Even a small black hole is extraordinarily dense and massive. If Earth was (hypothetically)crushed into a black hole, it would be under an inch across. Yet there are black holes in the universe bigger than our solar system, and bigger than thegiant Andromeda galaxy. ...
The Milky Way galaxy is estimated to contain 100 million stellar black holes -- cosmic bodies formed by the collapse of massive stars and so dense even light can't escape. Until now, scientists had estimated the mass of an individual stellar black hole in our galaxy at no more than 20 ti...
Solar system testperihelion precessiondeflection of lightIn the present paper we study the static and spherically symmetric dilaton-axion black hole in the testing ground of the Solar system. We constrain the parameters of the string motivated dilaton-axion form of the classical tests of general ...
hole remains forever hidden inside its event horizon. The greater the mass, the larger the black hole and its horizon. For a mass equivalent to the Sun, the event horizon has a diameter of almost three kilometres and, for a mass like that of the Earth, its diameter is just nine ...
Astronomers fromMIT, Italy, theCzech Republic, and elsewhere have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light-years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state...
This dormant black hole is about 10 times more massive than the sun and is located about 1,600 light-years away in the constellation Ophiuchus, making it three times closer to Earth than the previous record holder. “Take the solar system, put a black hole where the sun is, and the sun...
Just last year, astronomers published the first-ever picture of a black hole and its event horizon, a 7-billion-solar-mass beast at the center of the M87 elliptical galaxy. It’s over a thousand times bigger than the black hole in our galaxy, whose...
black hole of this class found in the Milky Way was a black hole in an X-ray binary in the Cygnus constellation (Cyg X-1), whose mass is estimated to be around 20 times that of the sun. The average stellar-mass black hole in theMilky Wayis about 10 times heftier than the sun....
