The LIGO/VIRGO/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. It has now announced the detection of a signal indicating a ...

In a recent issue of Science Magazine, the High Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists reports the discovery of another new type of very high energy (VHE) gamma ...

The X-ray-emitting binary system Cygnus X-3 features a massive star donating matter to a compact object, probably a black hole. That may explain its perplexing brightness. When you purchase through ...

A team of scientists found a compact object 40,000 light-years from Earth that is either a very massive neutron star or an itsy-bitsy black hole, but they’re not sure which. The so-called mass gap ...

During the height of the cold war in 1967, the Vela military satellites of the United States observed mysterious flashes of gamma rays. Due to the lack of information regarding their origin, the ...

The evolution of stars and their interactions with compact objects, such as black holes and neutron stars, remain pivotal in our understanding of the cosmos. Stellar evolution describes the life ...

As part of the Decadal Survey on Astronomy and Astrophysics (Astro2020), the Panel on Compact Objects and Energetic Phenomena will identify and articulate the scientific themes that will define the ...

The best observations so far of the dusty gas cloud G2 confirm that it made its closest approach to the supermassive black hole at the center of the Milky Way in May 2014 and has survived the ...

Researchers who used a telescope in South Africa report discovery of an object in the Milky Way that could either be the most massive neutron star ever observed, or the least massive black hole.

Out in the depths of the universe, outlandish black-hole-like entities might exist with the power to redefine physics as we know it. A new study calculates that, in the coming years, gravitational ...
