Supermassive black holes may control the growth of entire galaxies. New research shows that narrow plasma jets can travel hundreds of thousands of light-years, reaching the gas surrounding galaxies and creating directional regions of glowing ionized hydrogen.By heating and disrupting this cold gas, black holes can suppress star formation and regulate how galaxies evolve. A tiny region at the center of a galaxy may ultimately shape its entire cosmic environment.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
