Quasars are the brightest objects in the universe, not because they generate light themselves, but because gas spiraling into a black hole at extreme speeds creates friction that heats the gas to millions of degrees, producing more light than entire galaxies; the black hole remains dark while its surrounding accretion disk becomes the most luminous cosmic phenomenon.

Light from darkness #space #science #quasars #blackhole #universe #astronomyAdded:
It starts with the strangest glow in the universe coming from something that doesn't even make light. A quasar shines because a black hole is eating too fast.
Gas spirals inward so quickly that it rubs against itself, heats up to millions of degrees, and blasts out more light than entire galaxies. The black hole stays [music] perfectly dark, yet the cosmic dinner plate around it becomes the brightest thing anyone can see. It's like watching a lamp powered entirely by chaos, and if that blew your mind, like, comment, [music] and subscribe for more stories like this.
