Reaction Dynamics intends to launch its Aurora-8 rocket from the Canadian launch site. Bachar Elzein, the CEO of Reaction ...

A group of astronomers has found a new way to detect merging neutron stars through the X-rays they give off. Their observation of a merging pair also matches predictions for the birth of a ...

Eight years, three states, and two jobs after NASA's 2017 launch of its Neutron Star Interior Composition Explorer, or NICER, ...

The first-ever neutron star merger detected by gravitational waves is still giving off X-rays and scientists aren't sure why.

The Africa Nebula is a supernova remnant linked to Circinus X-1, an X-ray-emitting neutron star. It also surrounds the companion star that Cir X-1 orbits.

Interstellar echoes from a flaring neutron star have allowed astronomers to solve a mystery -- pinpointing the star's location.

NASA has unveiled a breathtaking new image showing what appears to be a massive “cosmic hand” stretching across 150 ...

Scientists have reported mysterious X-ray emissions where, more than three years ago, they spotted the first known collision of two neutron stars.

The X-ray binary system Vela X-1 consists of a neutron star (which contains as much mass as our sun (~1030 kg), but is very compact and has a radius of ~10 km or so, about the size of a small city) ...

Neutron stars and black holes that are part of a binary system sometimes emit strongly in the X-ray part of the spectrum. One of the problems is that the accretion disc (a disc of material ...

Neutron stars, as their name implies, are made of neutrons, but astrophysicists have not been able to rule out the possibility that they may also contain other exotic forms of matter. Now a team of ...

Neutron stars may not remain a mystery for much longer, as an x-ray pulsar named J1749.4-2807 may yet reveal their secrets.
