Answer:
A galactic supermassive black hole is a huge black hole at the center of a galaxy.
Step-by-step explanation:
A galactic supermassive black hole is a huge black hole at the center of a galaxy. It is millions to billions of times heavier than the Sun.
Supermassive black holes are formed when massive stars collapse at the end of their lives. They can grow even larger by merging with smaller black holes or by eating matter from their surroundings.
Supermassive black holes have a strong gravitational pull that affects their host galaxies. They can also power active galactic nuclei (AGNs), which are some of the brightest objects in the universe.
