A neutron star merger is the stellar collision of neutron stars. When two neutron stars fall into mutual orbit, they gradually spiral inward due to the loss of energy emitted as gravitational radiatio

A neutron star is the gravitationally collapsed core of a massive supergiant star. It results from the supernova explosion of a massive star—combined with gravitational collapse—that compresses the co

Image of the Crab Nebula taken by the Hubble Space Telescope. The wind echo of the Crab Pulsar can be seen on the center-right of the image.
Radiation from the rapidly spinning pulsar PSR B1509−58 makes nearby gas emit X-rays (gold) and illuminates the rest of the nebula, here seen in infrared (blue and red).
