"Transitional millisecond pulsars are cosmic laboratories that help us understand how neutron stars evolve in binary systems." ...

Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun.

"Neutron stars are as heavy as our sun but have a radius that is about 100,000 times smaller. As such, they are the densest objects in the universe.

The supernova that gives rise to a neutron star imparts a great deal of energy to the compact object, causing it to rotate on its axis between 0.1 and 60 times per second, and up to 700 times per ...

A neutron star with an identity crisis. NASA’s Neil Gehrels Swift Telescope discovered the 31st magnetar, Swift J1818.01607 or J1818 for short, in March 2020.

Neutron stars are the classic example of a synthesis between quantum mechanics and gravity. Formed after the collapse of the remnants of a supernova, a neutron star is generally smaller than the ...

Astronomers have spied the heaviest neutron star to date 3,000 light-years away from Earth. The “black widow,” a dense, collapsed star that’s devouring its stellar companion, also spins 707 ...

The neutron star, known as PSR J0952-0607, was discovered in 2017 about 3,000 light-years from Earth in the constellation Sextans. Recent measurements show the star weighs 2.35 times as much as ...

It wasn’t previously assumed that neutron stars could be as small as HESS J1731-347, so even if the strange star theory doesn’t pan out, this is still a weird neutron star either way.

Nothing inspires stellar awe quite like a neutron star.Often stretching only 15 miles across, these dead, collapsed stars can contain up to 2.5 times the mass of our own Sun (which is 865,000 ...

When the ESS gets up and running, it will initially be home to 15 neutron-based instruments—many of which have very good names like ODIN, BEER, T-REX, and BIFROST)—each of which will be set up ...
