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 ...

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 ...

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 ...

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 ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, ...

"If axion clouds, and thereby axions, are discovered, this would be a massive step toward solving the dark matter problem." When you purchase through links on our site, we may earn an affiliate ...

Fragmenting planets sweeping extremely close to their stars might be the cause of mysterious cosmic blasts of radio waves. Milliseconds-long fast radio bursts, or FRBs, erupt from distant cosmic ...

Launched on Sept. 6, 2023, XRISM studies X-ray signals emitted throughout the universe. On Feb. 25, 2024, it aimed at a ...

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 ...
