“We found that if a neutron star merger were to occur within around 36 light-years of Earth, the resulting radiation could cause an extinction-level event,” University of Illinois Urbana ...

NASA artist’s conception illustrates the aftermath of a "kilonova," a powerful event that happens when two neutron stars merge. These events could decimate life on Earth if we were too close to one.

Hiding within the huge catalog of newly found pulsars are several "spider pulsars," or neutron stars that devour their companion stars. The Fermi gamma-ray space telescope has discovered around ...

The Vela pulsar is one of the best-studied spinning neutron stars and is an example of the extreme nature of these objects. Created in a supernova around 10,000 years ago, the neutron star has a ...

These images show the merger of two neutron stars simulated with a new supercomputer model. Red colors indicate lower-density regions. The green and white ribbons and lines represent magnetic fields.

These sources emit ionizing radiation, typically in the form of alpha and beta particles, gamma rays or neutron radiation. Click here to learn more about radiation. Until the 1950s, only ... magenta ...

They have been detected since the 1960s, and astronomers thought they knew enough about the phenomenon to suspect this gamma ray was emitted by two neutron stars colliding far off in space.

In a major breakthrough, scientists have simulated in unprecedented detail how a neutron star cracks just seconds before being swallowed by a black hole. The simulation, led by Caltech ...

NASA's X-ray space telescope IXPE has made the first observation of polarized light emerging from an outbursting magnetar, neutron stars that possess the universe's strongest magnetic fields.

3D tomography with neutrons and X-rays In their new study, Prof Sascha Oswald (University of Potsdam) and Dr Christian Tötzke (University of Potsdam and HZB) have now presented a method to answer ...

Last November, astronomers saw a quick gamma-ray explosion lasting one-tenth of a second. Then, 13 seconds later, they knew it came from galaxy M82, which is just 12 million light-years away ...
