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 ...

Microquasars in our Milky Way galaxy have emerged as the most extreme particle engines, accelerating cosmic rays to unprecedented energies. These compact objects, found in binary star systems, rival ...

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 ...

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 ...

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 ...
