A study has revealed that galaxies possess a regulatory mechanism similar to a heart and lungs, which controls their growth by limiting gas absorption.
This mechanism, involving a supermassive black hole and its jet emissions, prevents galaxies from expanding too rapidly, ensuring their longevity and preventing premature aging into “zombie” galaxies.
Galaxies avoid an early death because they have a “heart and lungs” which effectively regulate their “breathing” and prevent them from growing out of control, a new study suggests.
