Roger Penrose suggested black holes might release energy. He proposed that near a rotating black hole’s outer zone—called the ...

Astronomers confirm a wandering black hole in our galaxy’s Sagittarius region using Hubble and Gaia microlensing data.

Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away from Earth.

A team of US astronomers led by Kailash Sahu said they have finally discovered the first isolated stellar-mass black hole ...

Astronomers have confirmed a wandering black hole, about seven times the mass of the Sun, 5,000 light-years from Earth.

While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star’s light and slowly ...

Without a buddy, this black hole made itself known through a different mechanism, called gravitational microlensing.

When British physicist Roger Penrose suggested in 1969 that energy could be pulled from a rotating black hole, it sparked a ...
