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, ...

It isn’t a secret that humanity and everything around us is made of star stuff. But not all stars create elements equally. Sure, regular stars can create the basic elements: helium, carbon, neon, ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, ...

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 ...

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

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

Neutron star mergers are also accompanied by flashes of light ... their orbits tighten due to the loss of angular momentum from the system. This leads to the two black holes eventually colliding and ...

On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. This huge ...
