Neutron star collision offers new source of gravitational waves
Astronomers have discovered a collision of neutron stars that released both a stream of gravitational waves and a flash of light, backing one of Einstein's theories.
LIGO gravitational wave discoverers win 2017 Nobel Prize in physics
Rainer Weiss, Barry C. Barish and Kip S. Thorne have won the 2017 Nobel Prize for physics for leading the projects that discovered gravitational waves and proved an century-old Einstein theory.
Einstein’s theory and ‘bent light’ reveal a way to weigh stars for first time
Rather than expose whether celestial objects need to go on a diet, this new weight scale offers a chance to learn more about the life cycle of stars, including our sun.
‘Dancing’ black holes yield stellar object as massive as 49 suns
Astronomers announced they have detected another gravitational wave tearing through spacetime, changing of our understanding of black holes and other stellar phenomena.
The second confirmation of ripples in spacetime is announced by astronomers at the Laser Interferometer Gravitational-Wave Observatory (LIGO).
February saw one of the most important astronomical breakthroughs of the decade, as a team of scientists “heard” gravitational waves -- a key postulate of Einstein’s theory of relativity -- for the first time in human history. Now, astrophysicist Janna…
Gravitational waves -- ripples in the fabric of spacetime -- aren’t just an Einstein theory any more. A team of international scientists announced Thursday that they confirmed the waves’ existence after recording feedback from a black hole collision a billion…
One theoretical physicist explains why today's announcement about gravitational waves is so profound.
Scientists with the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced on Thursday at a much-anticipated press conference in Washington, D.C. that the more than half-century search for gravitational waves has finally succeeded.
