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 ...

An international effort led by astrophysicists at the Niels Bohr Institute, University of Copenhagen, and the Technical University of Denmark has identified a distant object with properties that lie ...

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 ...

A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with other researchers, has developed a new method to estimate how stellar-mass compact objects ...

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 ...

Scientists from Moscow Institute of Physics and Technology, the Institute for Theoretical and Experimental Physics, and the National Research University Higher School of Economics have devised a ...

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.
