The largest neutron stars ever confirmed (before now) had around twice the mass of the sun. Using a new method, though, a group of scientists has found one with a mass 2.3 times that of the sun.

Scientists just found the biggest neutron star (or smallest black hole) yet in a strange cosmic collision. News. By Meghan Bartels published 23 June 2020 Whatever it is, scientists are excited.

Neutron star interiors likely have two or more separate zones dictated by increasing densities and pressures deep inside, analogous to Earth’s plastic mantle and molten core. The mathematical ...

Its companion star has been stripped almost bare, losing perhaps 98% of its mass to the black widow, leaving it at about 20 times the mass of our solar system's largest planet Jupiter - a far cry ...

A team of scientists found a compact object 40,000 light-years from Earth that is either a very massive neutron star or an itsy-bitsy black hole, but they’re not sure which.

‘Black widow’ neutron star found to be heaviest known pulsar after it devoured neighbour. At 2.35 times that of the Sun, pulsar is close to the upper limit of neutron stars, scientists say ...

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts. Neutron stars' surface gravities are so intense that the largest "mountains" are only a ...

It’s most likely either the biggest neutron star we’ve ever see or the smallest black hole we’ve ever seen. Either way, it’s a big deal to the astronomical community.

A neutron star is born when a massive star runs out of nuclear fuel and its gravity causes the core to collapse inward. The overwhelming force of the star’s mass on the core compresses it to ...

Neutron stars' surface gravities are so intense that the largest "mountains" are only a few millimeters tall. And those surfaces are already alien, consisting of a crust of heavy atomic nuclei ...
