As the collapsed core of a massive star, a neutron star is a small but incredibly dense object, packing up to three times the ...

Neutron stars, these cosmic remnants resulting from the catastrophic explosion of massive stars, represent one of the most ...

Intense gravitational lensing means you’d be able to see much more of a neutron star standing on its surface than you would ...

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 ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is predicted to account for most of the universe's mass. As it cannot be detected and studied using ...

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

But most of the gold on Earth isn’t in our hands; it’s deep underground. During the planet’s formation, heavy elements like gold and platinum sank toward the molten iron core. Geologists estimate that ...

V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

NASA's NICER telescope halts its mission after a key motor fails; engineers attempt to salvage eight years of space science.
