Launch is extremely constrained and that is exactly the situation we predicted."

A single teaspoon (or sugar cube) of neutron-star material would weigh roughly a billion tons on Earth — about as much as a mountain. NASA puts it at ~1 billion tons per sugar cube, while other sources cite up to 6 billion tons per teaspoon.…

Scientists have discovered that a simple mechanical squeeze can dramatically alter the magnetic properties and electrical behavior of exotic materials called altermagnets.…

Nearly everything has angular momentum, so even massive, self-gravitating objects don't become perfect spheres. Which one comes the closest?

For now, the existence of a mirror universe cannot be confirmed, say physicists at the PSI

Magnetars are neutron stars with magnetic fields a thousand times stronger than normal. One way that magnetars might form is through the merger of two small neutron stars.

We cannot measure the slowing of time near the Big Bang because there is no “cosmic clock” outside of this event against which to compare.

Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way

A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare…

New observations show that at least some gamma-ray bursts happened in galaxies that are just too faint to easily see.

A state of matter last seen just after the Big Bang may exist inside neutron stars
