Binary black hole spin behavior revealed using novel techniques

Research done at Cornell University has uncovered from gravitation wave data the first potential signs of spin-orbit resonances in binary black holes, a step toward understanding the mechanisms of supernovas and other big ...

Hubble lends a helping hand

Far above rain clouds, light pollution, and atmospheric distortion, NASA's Hubble Space Telescope has a clear view of the universe. It has shown us distant galaxies, tracked interstellar objects as they soar through our solar ...

Astronomers spy quartet of cavities from giant black holes

Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA's Chandra X-ray Observatory. This unusual set of features may have been caused by eruptions from two supermassive black ...

Gravitational wave

In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from the source. Predicted by Einstein's theory of general relativity, the waves transport energy known as gravitational radiation. Sources of gravitational waves include binary star systems composed of white dwarfs, neutron stars, or black holes.

Although gravitational radiation has not yet been directly detected, it has been indirectly shown to exist. This was the basis for the 1993 Nobel Prize in Physics, awarded for measurements of the Hulse-Taylor binary system. Various gravitational wave detectors exist.
