In recent years, black holes have transitioned from being exotic theoretical objects to well-observed phenomena in the ...

New research suggests that black holes may actually be "frozen stars," bizarre quantum objects that lack a singularity and an ...

What would happen if two black holes moved extremely close to each other? It’s a question NASA scientists are pondering after ...

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end ...

Astronomers have observed three types of black holes in the universe. Stellar-mass black holes formed from the collapse of a ...

Spanning 23 million light years, or 220 Milky Way galaxies, a set of giant, newly discovered black hole jets known as Porphyrion may change our understanding of black holes and the structure of the un ...

Sep. 17, 2024 — 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.

NASA’s Hubble Space Telescope and the Chandra X-ray Observatory have detected a pair of supermassive black holes in tight ...

At just 300 light-years apart, these are the nearest confirmed pair of supermassive black holes spotted in our local universe using visible and X-ray light observations.

This is the closest pair detected in the local universe using multiwavelength (visible and X-ray light) observations.

then produce a high-pitched "chirp" of these spacetime ripples when they collide and merge, usually creating a more massive black hole "daughter." Supernovas caused by the accelerating collapse of ...
