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 ...

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 ...

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 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 ...

Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or ...

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 ...

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 ...

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 ...

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 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 ...
