Gravitational Waves: The latest discoveries and star crash news
Gravitational waves are ripples in space-time created by the interaction of massive objects in space, such as black holes and neutron stars. Their existence was first predicted by Albert Einstein in his 1916 paper describing his theory of general relativity. In 2015, scientists made the first detection of gravitational waves, observing ripples from the collision of two black holes. The discovery won astrophysicists Kip Thorne, Barry Baris and Rainer Weiss the 2017 Nobel Prize for Physics. Subsequent observations have also detected gravitational waves from colliding neutron stars. Learn more about gravitational waves here.
A new paper suggests we may finally be able to uncover the identity of dark matter using the same technology that detects ripples in space-time known as gravitational waves.
The triple-spacecraft gravitational wave detector, named LISA, has received the go-ahead to become the first mission to detect spacetime ripples from space.
The recently detected gravitational waves are a muddled mix of various sources, new study finds.
Black holes are some of the most powerful objects in the universe — and humans could devise ways to harness that power as an energy source, a new theoretical study claims.
Collisions between neutron stars are the most powerful and violent events in the known universe. Would life on Earth survive a kilonova event?
Researchers have used a special crystal to bend the trajectory of light like a black hole would, a phenomenon known as 'pseudogravity.'
The sensitivity of LIGO has squeezed the quantum limit, meaning it can now detect merging black holes and neutron stars on smaller scales and at greater distances than ever before.
The new Siena Galaxy Atlas is an information gold mine for astronomers and a free gallery of galaxy portraits for the public.
