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 ...

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 bewilderingly powerful mystery object found in a nearby galaxy and only visible so far in millimeter radio wavelengths could be a brand new astrophysical object unlike anything astronomers have seen ...

EVANSTON, Ill. (CBS) -- Northwestern University astrophysicists were among those involved in an international research collaboration that has detected a gravitational-wave signal caused by a merger of ...

This X-ray binary system is like a scale model of some of the most luminous quasars in the universe. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

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 ...

X-ray binaries are systems formed by a compact object, a neutron star or a black hole, and a star of a similar size to the Sun. The compact object swallows matter from the companion star through a ...

Astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team's novel technique might also ...

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.

Astronomers have detected an unusually powerful and compact object in a nearby galaxy, one so bright and unique that it may represent an entirely new class of cosmic phenomena. The source, named ...
