New research suggests that the heart of the Milky Way may be dominated by a dense clump of dark matter rather than the ...

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.

Astronomers overwhelmingly agree a supermassive black hole anchors the Milky Way. But a new theoretical analysis explores a far more speculative possibility: not a black hole, but a dense knot of dark ...

Add Yahoo as a preferred source to see more of our stories on Google. They’re the boogeymen of science fiction, a paradox of science and quite possibly a key to understanding the universe. Scientists ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Astronomers have discovered potentially the most massive black hole ever detected. The cosmic behemoth is close to the theoretical upper limit of what is possible in the universe and is 10,000 times ...

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on itself and formed a black hole.

Astronomers tracked a star in Andromeda as it dimmed and vanished without the usual fiery explosion, offering rare clues to how black holes form.

A distant black hole tore apart a star and then stayed active for years, emitting powerful energy that continues to grow.

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.
