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

When the remnants of two stars collide, their union can launch a dazzling jet of high energy matter. A new computer simulation reveals how the merger, which forms a black hole, emits that bright beam, ...

It's not science fiction: Scientists have discovered a neutron star that spins faster than any blender humans have ever made. In a recently published study, scientists discovered that the 4U 1820-30 ...

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 ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of ...

New research suggests that colliding neutron stars can briefly "trap" ghostly particles called neutrinos, which could reveal new secrets about some of space's most extreme events. When it comes to ...

How long do free neutrons live until they decay? This has been a hotly debated topic, because different measurement techniques lead to different results. A possible new solution has now been proposed: ...

Using gravitational waves, tiny ripples in space-time first predicted by Albert Einstein back in 1915, astronomers have discovered that a "stellar graveyard" is packed with mergers between extreme ...
