NASA's flagship space telescope captured flares from the disk of superheated material around the black hole, revealing the dynamic—and explosive—physics at our galaxy's core.

Astrophysicists have observed our central supermassive black hole. They found the accretion disk is constantly emitting flares without periods of rest. Shorter, faint flares and longer, bright flares ...

Researchers at the University of Twente have solved a long-standing problem: trapping optically-generated sound waves in a standard silicon photonic chip. This discovery, published as a featured ...
