The violent merger of two neutron stars is thought to involve three main energy-transfer processes, shown in this diagram, that give rise to the different types of radiation seen by astronomers, ...

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

Physicists have measured the microscopically thin skin of neutrons enclosing the insides of atoms of lead for the first time, finding that it's thicker than expected. The discovery could help to ...

If neutron stars are to be used to detect elusive dark matter, two neglected effects will need to be factored in. The matter we see around us makes up only 15% of the Universe’s mass — the other 85% ...

Astronomers have added a new species to the neutron star zoo, showcasing the wide diversity among the compact magnetic remains of dead, once-massive stars. While it’s an oddball, some of this newfound ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...

Imagine that a massive star, one far bigger than our own sun, has died. First there is a spectacular explosion, followed by whatever remains. Sometimes it is a black hole, which can be fascinating in ...

A discovery involving researchers at The University of Hong Kong (HKU) has, for the first time, revealed millisecond ...

See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...

The universe may contain extremely dense and exotic hypothetical cosmic objects known as strange quark stars. While astrophysicists continue to debate quark stars' existence, a team of physicists has ...

When certain large stars use up all their nuclear fuel and die, they collapse and detonate, creating a supernova. These end-of-life events are some of the most energetic in the universe, and send ...

Neutron stars are very small and dense stars, where roughly half a million earth masses of material are squeezed into a city-sized volume with a radius of 10 km. They are mostly composed of neutrons ...
