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 ...

Woven through the universe are forces, often unseen, that dictate its grand design. For example, at the very heart of nearly ...

At the center of the Milky Way, a supermassive black hole hides behind veils of dust, gas, and warped spacetime. Now a ...

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

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

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

XRISM measurements map gas velocities in the Perseus and Virgo clusters, separating black hole-driven turbulence from merger-driven motion using high-resolution X-ray spectroscopy.

What: New analyses using early observations from the European Space Agency’s Euclid mission examine how galaxy mergers trigger active galactic nuclei (AGN), luminou ...

Some evidence of supermassive black holes influencing the gas around them has previously been seen in X-ray images. However, ...

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 ...

Astronomers have traced the origin point of a jet of material that is thousands of light-years long emanating from the supermassive black hole M87* ...

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond.
