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

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 ...

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 ...

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to ...

Our Milky Way galaxy may not have a supermassive black hole at its center but rather an enormous clump of mysterious dark ...

There's no denying that something massive lurks at the heart of the Milky Way galaxy, but a new study asks whether a ...

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.

Confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics ...

Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The so-called "sleeping giant," named Gaia BH3, has a mass that ...

There is a lot we have yet to understand about the center of the Milky Way—could it be due to a mass of invisible dark matter?

The most recent CSC update adds more than 400,000 unique compact and extended X-ray sources, as well over 1.3 million individual X-ray light detections collected through 2021. The latest examples from ...
