Pulses from over 100 rapidly spinning neutron stars were timed to spot a phenomenon theorized by Einstein.
Calculations by a gravitational wave hunter suggest that the early universe was more developed than what we can observe.
Cocoons of debris surrounding collapsing stars may generate gravitational waves detectable by LIGO.
They're not called "supermassive" black holes for nothing, as a video from NASA illustrates.
A higher-resolution view is helping scientists understand the physics behind the strangest objects in the universe.
The theorized object warps spacetime like a black hole but still releases light.
Machine learning has boosted the resolution of an image produced by Event Horizon Telescope data captured six years ago.
A rare ‘ultramassive’ black hole, 30 billion times the mass of the Sun, is lurking in the cosmos.
Using the world-spanning Event Horizon Telescope, researchers were able to study an enormous jet of electromagnetic radiation.
The jet is from the most distant tidal disruption event yet observed.
The dense, dormant object is hiding in plain sight.
These are the IXPE mission’s first observations of a mass-accreting black hole.
The black hole ejected stellar material in 2021, three years after pulling a star into its orbit.
It's the second major view of a black hole to come out of the Event Horizon Telescope.
In these binary systems, a star is slowly eaten as it death-spirals around a black hole.
The Event Horizon Telescope Collaboration has some mystery news to share next week.
The "Reverberation Machine" is helping scientists detect outbursts from black holes.
Pulsars scattered throughout the galaxy provide a novel way to see ripples in spacetime.
Astronomers say it's the most misaligned black hole they've ever seen.
The team of astrophysicists found that 1% of ordinary matter may be stored away in the lightless spheres.
