The bold question-askers at What If warn how a black neutron star could destabilize Earth’s orbit and wreak havoc.

When two stars orbit one another in such a way that one blocks the other's light each time it swings around, that's an eclipsing binary. A new paper from NASA's Eclipsing Binary Patrol citizen ...

A pair of objects 20,000 light‑years away has just broken the energy ceiling for light inside our galaxy. These twin bodies (a massive star and a black hole), known as a microquasar, are generating ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, and short-lived black hole pulsars.
