Gravitational waves identify what could be a rare one-in-1000 event. Astronomers at Cardiff University have identified a strange twisting motion in the orbits of two…
Imagine taking a star with twice the mass of the Sun and crushing it down to the size of Manhattan. The result would be a…
The Gravitational Constant The gravitational constant G determines the intensity of gravity, the force that pulls the Earth in its orbit around the sun or…
A new technique to measure vibrating atoms could improve the precision of atomic clocks and of quantum sensors for detecting dark matter or gravitational waves….
In the last few years, astronomers have achieved an incredible milestone: the detection of gravitational waves, vanishingly weak ripples in the fabric of space and…
Deep Follow-up of GW151226 — an ordinary binary or a low-mass ratio merger? Now that we’ve been detecting gravitational waves (GWs), we’d like to better…
Gravitational waves are ripples in the curvature of spacetime caused by accelerated masses that propagate as waves at the speed of light outward from their…
New laser breakthrough to help increase understanding of gravitational waves. Scientists have created a proof-of-concept setup of a new laser eigenmode sensor that offers over…
Less than one percent of stars in a galaxy are formed with masses exceeding ten solar masses. Despite their rarity, massive stars are believed to…
Lasers support certain structures of light known as “eigenmodes.” An international collaboration of experts in gravitational waves, metasurfaces, and photonics has pioneered a new method…
One of the biggest puzzles in modern cosmology is the existence of dark matter, which constitutes most of the matter in the universe. Recent research…
Simulation Shows How Star Collisions Fuel Massive Black Holes New model shines light on the mysterious origins of Gravitational Wave 190521. It’s challenging to predict…
NASA’s FERMI Satellite Hunts for Extremely Long-wavelength Gravitational-Wave Signals Coalescing supermassive black holes in the centers of merging galaxies fill the universe with low-frequency gravitational…
The finding hints at exotic black hole behaviors. In the last seven years, scientists at the LIGO-Virgo Collaboration (LVC) have detected 90 gravitational waves signals….
Gravitational-waves are ripples in space-time created by distant astronomical objects and detected by large complex detectors (like LIGO, Virgo, and KAGRA). Finding gravitational-wave signals in…
A new method of identifying gravitational wave signals using quantum computing could provide a valuable new tool for future astrophysicists. A team from the University…
What Are Gravitational Waves? Gravitational waves are distortions in spacetime that result from the movements of objects with mass. Gravitational waves are not simple conceptually,…
NASA’s Chandra X-ray Observatory continues to study GW170817, a neutron star merger that produced gravitational waves. Many telescopes saw different kinds of light after the…
