Black Widow Neutron Star Is the Heaviest Ever Seen

Black Widow Neutron Star Is the Heaviest Ever Seen

A condensed collapsed star has chewed up and eaten almost the total mass of its stellar companion. In so doing, it has become the heaviest neutron star observed to date.

Photoionised Quasar Ghosts Found by Hubble

The Hubble Space Telescope has documented a set of enigmatic quasar ghosts. These ethereal green images mark the graves of these objects that flickered to life and then faded.

Triple Star System Pulsar Enables Complex Gravitational Measurements

Triple Star System Pulsar Enables Complex Gravitational Measurements

Using the Green Bank Telescope, astronomers have revealed a novel stellar system. Consisting of two white dwarf stars and a superdense neutron star, the stars are packed within a space smaller than Earths orbit around the Sun.
