See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a ...

We previously covered one such “gravity telescope” with the Laser Interferometer Gravitational-Wave Observatory (LIGO). Another one is the Japanese project Kamioka Gravitational Wave Detector (KAGRA).

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

The fabric of spacetime can be distorted by immense gravity, and black holes show the most extreme version of this, where density appears infinite and physics begins to collapse.

Ripples in spacetime now give astronomy a second sense. The network listens to collisions, maps a low-frequency background ...

Simulations reveal that the mixing of neutrinos, during the collision of neutron stars, significantly alters how their merger ...

A companion star may have stripped silicon layers. This provided a new window into stellar death. Astronomers have observed the inner layers of a dying star through a rare type of stellar explosion ...

New simulations show that neutrino flavor transformations change both the composition and the signals left behind after neutron star collisions. When two neutron stars collide and merge, the result is ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic ...

When two neutron stars collide, they unleash some of the most powerful forces in the universe, creating ripples in spacetime, ...

Astronomers have witnessed a rare “extremely stripped supernova” that exposed the inner silicon layers of a dying star, confirming theories of stellar fusion and offering new insight into how ...
