How does a supermassive black hole affect the galaxy around it?
SpaceGalaxies
Quick Answer
It can regulate star formation by heating or expelling gas, especially when it is actively feeding. The black hole’s gravity also influences stars close to the galactic center.
The Full Story
Most large galaxies appear to host a supermassive black hole at their core, including the Milky Way’s Sagittarius A*. When material falls toward such a black hole, it can power an active galactic nucleus or quasar, releasing enormous energy. That energy can heat surrounding gas or drive outflows, which may limit how quickly new stars form. The black hole’s direct gravitational influence is strongest only in the inner region, but its feedback can shape the whole galaxy.
Key Facts
1.The Milky Way’s central black hole is Sagittarius A*
2.Quasars can outshine entire galaxies
3.Black-hole feedback can suppress star formation
