Could something even darker than a black hole lurk in the Milky Way’s core?
The object at the Milky Way’s center has long been treated as a settled case: a supermassive black hole called Sagittarius A* weighing about four million Suns and anchoring the galaxy’s structure. Now ...
For decades, the motions of stars near the center of our Milky Way Galaxy have been treated as some of the clearest evidence ...
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 ...

Scientists may have found a powerful new space object: 'It doesn't fit comfortably into any known category'
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 ...
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 ...
Team including Northwestern scientists detect waves caused by merger of neutron star, mystery object
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 ...
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 ...
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.
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 ...
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 ...
