Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.

Astronomers have discovered a black hole emitting energy in jets longer than the width of 140 Milky Way galaxies. An artist’s concept of Porphyrion, a jet of material 23 million light-years long that ...

A new paper explores the idea of asteroid-sized objects that may be causing gravitational ripples in our cosmic neighborhood.

The universe’s hidden mass may be made of black holes, which could wobble the planets of the solar system when they pass by ...

The citizen science app, available in eight languages, uses public input to identify kilonovae, neutron star mergers that ...

Astronomers from the National Central University in Taiwan have investigated an unusual superorbital period variation of an X ...

Astronomers have discovered a "missing link:" a tiny black hole lurking with a red giant star in a strange and ...

"The great hum" in the October 2023 issue states that astronomers weren't sure that supermassive black holes in binary systems could close in on each other. I would assume that objects with such ...

Black holes are on a continuum of ultradense objects that form from the remnant cores of dead stars after they run out of ...

In February 2016, scientists at the Laser Interferometer Gravitational-wave Observatory (LIGO) confirmed they made the first-ever detection of gravitational waves (GWs). These events occur when ...

That’s where X-rays come in. Most known black holes exist in binary systems, where they have a companion star. The black hole ...

Like two Sumo wrestlers squaring off, the closest confirmed pair of supermassive black holes have been observed in tight proximity.
