4About it
A black hole is a place where gravity is so strong that nothing that crosses its edge, the event horizon, can get out again, not even light. Gas that falls toward it swirls into a flat disk and gets hot enough to glow.
Tap it to feed it a star: the star spirals in faster and faster, is stretched into a streak and plunges in, and the disk flares. In 2019 astronomers showed the first picture of a black hole's shadow, at the heart of the galaxy M87, made with radio telescopes spread across the Earth.
