Black hole light echoes are an extreme form of gravitational lensing. To measure the masses and spins of black holes, ...

Supermassive black holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large ...

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from ...

Recent results suggest these exotic objects just might help us account for the mysterious force pushing the universe apart.

For the first time, NASA’s Swift Observatory has observed twin black holes disrupting a gas cloud in a galaxy’s center, ...

The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for ...

Black holes are fascinating objects. They're unimaginably dense: If Earth was (hypothetically) crushed into a black hole, it ...

Astronomers have used a range of telescopes, including Hubble, to watch as particles dance around a neutron star collision ...

Black holes exert a tremendous influence on their surroundings, meaning that when they spin, they literally drag the very fabric of space and time around with them. That means nothing can sit still ...

It's sitting in the middle of a galaxy called LID-568, as seen just 1.5 billion years after the Big Bang, appearing to guzzle ...

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the center of a ...

Astrophysicists have developed a method to detect light echoes from black holes, potentially revolutionizing the measurement ...
