Only a few dozen of these short-lived binaries exist in the galaxy at a time, making the serendipitous find extremely ...

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 ...

‘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 ...

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.

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.

In August 2017, humanity observed a wonder. For the first time, we got to see two neutron stars colliding, an event observed by telescopes around the world, alerted by the gravitational ruckus as ...

The staggering pressures that exist at the core of neutron stars may be like those that existed at the time of the big bang, but these states cannot be simulated on Earth. 4th of July Sale - 25% OFF!

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 ...
