Mystery solved: X-ray light emitted from black holes

Supported by 40 years of theoretical progress, astrophysicists have published research that finally bridges the gap between theory and observation, demonstrating that gas spiraling toward a black hole inevitably results in X-ray emissions. Read about their discovery, the exotic nature of black holes, and the technology uncovering the details of the widely accepted theory.
