Small and unassuming, Segue 1 is a nearby dwarf galaxy containing only a handful of stars—too few to provide the gravity ...

An unexpected monster black hole was found hiding inside one of the Milky Way's tiniest neighbors, rewriting what scientists ...

One of the Milky Way’s smallest galactic neighbours seems to have a supermassive black hole at its centre, upending ...

New research suggests a massive black hole is the primary force preventing Segue 1's small complement of stars from drifting ...

The nearby dwarf galaxy Segue 1 is exceptionally faint for its mass, which has puzzled astronomers almost since its discovery. A new paper proposes this could be because it hosts a ridiculously ...

Researchers have believed that Segue 1, a puny galaxy orbiting the Milky Way just 75,000 light-years away, was packed with dark matter, a substance in space that doesn't shine or interact with light.

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object ...

For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287.

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

Twin black hole collisions detected in 2024 have provided the sharpest-ever test of Einstein’s theory while revealing new details about how black holes form and spin.
