A massive filament of gas and dust, designated X7, has been elongated during its long approach to the Milky Way galaxy's supermassive black hole Sagittarius A*. See W.M. Keck Observatory imagery of X7 ...

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.

Recent observations suggest that 'runaway' black holes are tumbling through the cosmos. Building on decades of theory, the discovery adds a remarkable new chapter to the story of the universe.

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

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 ...

Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove ...

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 ...
