Astronomers have spotted the first evidence of a merger event that gave a black hole a kick that left it traveling at around 3 million mph — fast enough for it to escape its host galaxy.
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.
In a new analysis of their gravitational wave data, scientists with the international LIGO-Virgo Collaboration have discovered 10 new examples of merging binary black holes.
Telescopes that observe the universe in the most energetic form of light may help scientists detect the "fingerprints" of gravitational waves, new research reveals.
Around the world, astrophysicists are poring over the blips of gravitational waves that ripple through Earth when distant black holes or neutron stars collide. Most don't also attend high school.
Albert Einstein saw beyond human tribalism to an enlightened realm of tolerance. We can too: He left us clear directions for how to do it.
Take three black holes and throw them into the disk surrounding a supermassive black hole and things get really weird, really fast.
Europe's gravitational wave detector is expected to launch in 2037 to push forward a rapidly growing science field.
Scientists observed changes in the signals coming from rapidly-spinning stars called pulsars that might point to the existence of subtle space-time ripples vibrating throughout the entire universe.
Physicists turned on a new type of gravitational-wave sensor and saw two intriguing results, but they aren't yet ready to claim a discovery.
Scientists have used computer models to predict the size of minuscule deformations, or mountains, on the surfaces of neutron stars, which are responsible for causing gravitational waves as they spin.
The earliest and most momentous epoch in the history of the universe released a flood of gravitational waves, tiny ripples in the fabric of space-time.
Scientists hunting for elusive gravitational waves across the universe may be able to supercharge their discoveries with a new tool: artificial intelligence.
After more than four years of exploring a menagerie of cosmic happenings through gravitational waves, scientists have finally spotted the third expected variety of collision — twice.
Space.com caught up with Greene to discuss the importance of science education, why black holes are so interesting and whether a "theory of everything" breakthrough could be on the horizon.
A team has offered a way for gravitational wave events called dark sirens to resolve a crisis in cosmology
What if one mission could study the gravitational ripples triggered by some of the most violent events in the universe — on the way to observing the least-known planets of our solar system?
