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 ...

A mysterious object roughly 15,000 light-years from Earth is sending paired bursts of radio waves and X-rays toward our ...

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 Chinese research team has for the first time detected radio pulses from a long-term "radio-quiet" young neutron star - ...

The binary black holes in the universe are already astonishing enough, but researchers from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences have made a groundbreaking ...

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 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 ...

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 ...
