Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

For the first time, researchers have simultaneously measured the gravitational waves and the light from two merging neutron stars. ‘Multi-messenger astronomy’, combining the observation of ...

The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of researchers ...

In the depths of the universe, where black holes collide and neutron stars crash, invisible ripples in spacetime are sent across the cosmos, carrying with them secrets about the most extreme events in ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of ...

Neutron star mergers are among the most extreme events in the Universe. A recent simulation shows that the cataclysm begins well in advance. Indeed, a chaotic ballet of their magnetic fields is ...
