A team of European researchers has suggested that the Moon’s orbit could be used as a gigantic detector for gravitational waves. These waves, much smaller than those that existing detectors can pick up, could originate from the early universe.

A huge range of dark matter suspects are being investigated. In a new study, astronomers have searched for clouds of hypothetical ultralight particles that could congregate around black holes, and reveal themselves by sending out gravitational waves.

Astronomers have reported a bumper crop of new gravitational wave detections. The 35 new signals, comprising the third Gravitational-Wave Transient Catalog (GWTC-3), help scientists probe the depths of the cosmos in more detail.

Astronomers have proposed a novel solution to one of the many mysteries of black holes – why do so many seem to be more massive than expected? A new model suggests that their growth may be “cosmologically coupled” to the expansion of the universe.

It’s tricky detecting gravitational waves – these spacetime ripples are often drowned out by background vibrations from earthquakes and human activity. Now a pair of astrophysicists has proposed a new location that would be far quieter – the Moon.

Astronomers have detected the final piece of the gravitational wave trifecta – a black hole swallowing a neutron star. Two separate events rolled in just days apart, with the black holes gobbling up the stars like Pac-Man rather than Cookie Monster.

“Stationary” has very different meanings in quantum scales – an object that looks perfectly still to us is made up of bouncing atoms. Now, scientists have managed to slow down the atoms almost to a complete stop in the largest macro-scale object yet.

With elusive dark matter continuing to evade detection, scientists are having to search in stranger and stranger places. In a new study, physicists at MIT have studied the spins of black holes for signs of drag from dark matter slowing them down.

The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea. Now, a 13-year survey of light from pulsars scattered across the galaxy may have revealed the first hints of gentle gravitational wave background signals.

The LIGO and Virgo Scientific Collaboration has detected gravitational waves coming from the most massive black hole collision that it's ever recorded. The end result created a gargantuan black hole that belongs to a new class.

Classical physics describes how large objects and systems work on an everyday scale, while quantum physics describes the “spooky” subatomic world. Now scientists have observed a rare crossover where a quantum fluctuation affected a macroscale object.

Astronomers have observed a bright flash of light from space, which appears to have come from a collision between two black holes. And that’s surprising, considering that black holes are famously dark objects.
