Black Holes Shape Galaxies

#blackholes #galaxies #cosmicneighbors

Black holes are often described as cosmic destroyers, but their most important role is far quieter — and far more influential.

In this episode of Cosmic Neighbors, we explore how supermassive black holes help shape the galaxies that surround them. From regulating star formation to influencing the structure of entire galaxies, black holes act less like monsters and more like long-term cosmic regulators.

This episode focuses on what astronomers actually observe, how we infer the presence of black holes, and why nearly every large galaxy appears to host one at its center.

This is Episode 03 in the Cosmic Neighbors series.
