By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Was a powerful cosmic explosion seen by the Einstein Probe launched by a supermassive black hole snacking on a star, by a ...

The study of neutron stars and black holes is a fascinating area of astrophysics that explores some of the most extreme conditions in the universe. Neutron stars are incredibly dense remnants of ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

Nick Hague and Suni Williams spent six hours working on NICER, AMS and other equipment outside the International Space ...

a space-based observatory that detects and measures X-ray emissions from black holes, neutron stars, galactic clusters, and other extreme cosmic sources. They noticed that X-rays from the black ...

The first detections of continuous gravitational waves will open a new window on the universe and provide unique information on neutron stars, the densest objects short of black holes. These ...

Australian scientists have discovered a collapsed star called a neutron star that spins thousands of times slower than expected. The star, called ASKAP J1839-075, is one of a number of recent ...

That’s why all detections so far have been collisions between black holes or neutron stars. Those events are akin to throwing a pebble in a pond, but there are vibrations all the time.

Gamma-Ray Bursts (GRBs): Extremely powerful explosions in distant galaxies that emit vast amounts of energy, mainly as gamma rays. Hypernovae (Massive Star Explosions): Ultra-powerful stellar ...
