It was thought that the giant gamma-ray bubbles in our Galaxy were inflated by the supermassive black hole. But a computer simulation reproduced them without it. It turned out that ordinary stellar explosions are enough. This discovery promises new ways to study the turbulent life of galaxies.
🎯 Contrary to intuition, the bubbles’ light isn’t born from heat, but from particles flying almost at light speed.
