By zeroing in on the infrared scale, researchers offer details of the black hole jet stream in faraway galaxy M87.

As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the mass of our sun into a small volume. Models predict that neutron stars are about a dozen or so miles across, but their exact radius has always been unclear.

NASA has released a chilling audio clip that lets human ears experience the sound of a supermassive black hole, at least in a heavily modified form. The recording, generated from data captured in 2003,

The sounds aren't just a scientific curiosity, though. The tenuous gas and plasma that drifts between the galaxies in galaxy clusters – known as the intracluster medium – is denser and much, much hotter than the intergalactic medium outside galaxy clusters.

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely

A new study may visually solve an enduring mystery about a bright object that's been studied since the 19th century

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole.

It’s possible that these objects might be the primordial beginnings of the supermassive black holes found in the centers of most galaxies.

For the first time, astronomers have detected intense, fast-changing radio signals from a tidal disruption event, dubbed AT2024tvd, located outside its galaxy's core. Now, astronomers are trying to understand what the black hole is doing 2,
