Stars with a much larger mass than our Sun burn out after just a few million years; in a gigantic explosion known as a ...

The collision and merger of two neutron stars—the incredibly dense remnants of collapsed stars—are some of the most energetic events in the universe, producing a variety of signals that can be ...

Second only to black holes, neutron stars – incredibly dense star remnants – are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time in ...

What if the brightest explosion in the Universe was heading straight toward Earth? Would humanity have time to prepare, or ...

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 ...

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the ...

Neutron stars are among the most exotic and extreme objects in the universe. These fascinating remnants form from massive stars that have reached the end of their life cycles. When such stars exhaust ...

Scientists uncovered traces of plutonium-244 in deep-sea crust, revealing a continuous cosmic rain from a kilonova explosion that occurred over 100 million years ago.

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
