Some neutron stars may contain a "special type of matter," according to a new NASA study. These observations from NASA's Chandra X-ray Observatory indicate that the interiors of neutron stars might ...

New research describes how a kilonova explosion triggered by colliding neutron stars could eradicate life on Earth for thousands of years. Thankfully, the odds are incredibly low. When you purchase ...

Using NASA’s Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth — and possibly the closest. The ...

Being too close to two neutron stars colliding spectacularly may be catastrophic for a planet like Earth, scientists have calculated. This type of cosmic event is known as a kilonova and releases huge ...

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in ...

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become ...

WASHINGTON (Reuters) - When a star up to 20 times the mass of our sun exploded in a nearby galaxy, the blast was so violent that it was visible to the naked eye from Earth's southern hemisphere for ...

Gravity from mountains on rapidly rotating neutron stars produces ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) searches for such ...

Astronomers have caught a highly magnetic dead star, or "magnetar," in the Milky Way briefly acting like a pulsar, a type of neutron star that rapidly rotates. The magnetar put on its pulsar disguise ...
