What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

Chandra X-ray Observatory and X-ray Polarimetry Explorer (IXPE) imagery of the Milky Way's core and supermassive black hole Sagittarius A* has been sonified by SYSTEM Sounds. Credit: ...

The team discovered the star by analyzing archival data from NASA’s NEOWISE mission. They used a prediction from the 1970s that theorized that when a star underwent direct collapse, it would leave ...

A “disappearing” star in the Andromeda galaxy is the closest and best candidate for a newborn black hole that astronomers have ever seen ...

WASHINGTON, Feb 12 (Reuters) - The formation of a black hole can be quite a violent event, with a massive dying star blowing ...

"We are not just replacing the black hole with a dark object; we are proposing that the supermassive central object and the ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

Sagittarius A* may be a dense dark matter core instead of a black hole, offering a new explanation for the Milky Way’s central gravity.

Previous observations of stars whipping around an unseen mass—especially a bright star called S2—have pointed to an object ...

Researchers looking for signs of extraterrestrial life instead stumbled upon a pulsar at the center of the Milky Way galaxy.

If the pulsar is confirmed, it could enable more precise measurements of the space-time around the galaxy’s central supermassive black hole ...
