As NASA reports, two astronomers working with raw Webb data the space agency periodically makes available to researchers, ...

The largest black hole collision ever recorded has scientists' jaws on the floor — and scratching their heads.

Using ripples in space-time predicted by Einstein, a team of researchers has detected a cosmic merger of unprecedented ...

"It was something I’ve never seen before and I’ve looked at tens of thousands of images of galaxies over my career," he said.

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

"The biggest surprise of all was that the black hole was not located inside either of the two nuclei but in the middle. We asked ourselves: How can we make sense of this?" ...

Instead of a tempest in a teapot, imagine the cosmos in a canister. Scientists have performed experiments using nested, ...

Astronomers have detected the most massive black hole merger ever observed, challenging stellar evolution and black hole formation theories.

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions seen since the Big Bang.

With the help of NASA's Hubble Space Telescope, an international team of scientists has found more black holes in the early universe than has previously been reported. The new result can help ...

Supermassive black holes that seem too large to exist in the early universe may have grown from primordial black holes formed in the first second after the Big Bang.
