Скачать или смотреть what is the Evolution of a Galaxy?

Key aspects of galaxy evolution:
Mergers and Interactions:
Galaxies can collide and merge, either transforming into larger, more massive galaxies (like the case of elliptical galaxies) or creating irregular galaxies.
Star Formation:
Mergers and interactions can trigger bursts of star formation in galaxies, sometimes leading to ring galaxies or active galactic nuclei.
Passive Evolution:
Some galaxies evolve passively, becoming fainter and redder as their high-mass stars evolve, without significant mergers or interactions.
Galaxy Types:
Galaxies are classified into various types, including spiral, elliptical, irregular, and ring galaxies.
Evolutionary Progression:
There's a general progression from spiral galaxies to elliptical galaxies through mergers.
Observational Evidence:
Telescopes like Hubble and James Webb, have observed numerous examples of galactic mergers, providing evidence for ongoing galaxy evolution.
Supermassive Black Holes:
The supermassive black holes at the centers of galaxies can also be affected by mergers and can impact the evolution of their host galaxies.
