Using the Japanese-led X-ray Imaging and Spectroscopy Mission (XRISM), astronomers have taken a deep look into a fascinating ...

Despite their destructive forces, black holes are often seen in with a companion, such as a star, neutron star, white dwarf, ...

However, a study published Oct. 23 in Nature has found that the black hole binary system V404 Cygni, which contains a black hole and a small star, has an additional friend — a second star that ...

Astronomers have stumbled upon a pair of massive black holes in a distant galaxy that are triggering unusual bursts of light ...

Stellar-mass black holes typically form after a star goes supernova and collapses. However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture. This black ...

A research based on findings of the Neil Gehrels Swift Observatory reveales that strange recurring signals from a distant ...

The distant companion star is shown at the top of the image. (Courtesy: Jorge Lugo/MIT) For the first time, astronomers have observed a black hole in a triple system with two other stars. The system ...

Hypothetically, black hole masses can range all the way from ... “There’s a really basic orbital mechanics idea that if a binary system loses half its mass it becomes unbound,” writes ...

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 ...

In March 2021, astronomers observed a high-energy burst of light from a distant galaxy. Assigned the name AT 2021hdr, it was thought to be a supernova. However, there were enough interesting features ...
