V404 Cygni

V404 Cygni is a binary star system where a normal star orbits a black hole, gradually feeding it material. As the black hole pulls in this matter, it heats up and emits powerful X-ray and gamma-ray bursts. These energetic outbursts, observed in 2015 and other times, occur when the black hole's accretion process becomes unstable. V404 Cygni provides valuable insights into how black holes grow and influence their surroundings. Its dynamic activity helps scientists study extreme physics and the behavior of matter under intense gravitational forces.
