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.

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

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 ...

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

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

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.

Hubble catches a spiral galaxy mid-flight, shedding glowing gas as it battles the harsh environment of a nearby galaxy ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

However, there's another point in fermionic dark matter's favor. The Gaia spacecraft's map of the Milky Way – the most ...

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

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth&rsquo ...

A supermassive black hole is on track to produce the longest recorded emission of energy left over from a shredded star.
