"Light Echoes" Prove That This Neutron Star is Weirdly Like a Black Hole

Between rainbows, rings, and sharp, hard lines, it’s difficult to not clap my hands in glee while unpacking the levels of awesome crammed in this X-ray image of Circinus X-1. The beautiful bullseye light echoes hint this neutron star is farther, brighter, and more like a black hole than we thought. »6/25/15 7:00pm6/25/15 7:00pm

Stellar Carnage as Neutron Stars Collide

When two neutron stars collide, they viciously shred each other before merging into a black hole punctuated by a gamma ray burst. A new supercomputer simulation sets a mismatched pair of neutron stars in a death-spiral to investigate the process. The merger completes in seconds, ringed by a halo of diffuse gas. »5/13/14 11:15am5/13/14 11:15am

Neutron star observed creating otherwise impossible form of matter

Neutron stars are the unimaginably dense remnants of collapsed giant stars. They get their name because the conditions inside are so fierce that atoms are smashed apart into a soup of protons, electrons, and, yes, neutrons. And now we have the first direct evidence that neutron stars are forming superfluids of… »2/06/11 1:20pm2/06/11 1:20pm
