Six Types of Galaxies Explained in 6 Minutes

Discover the six major types of galaxies, from the smallest cosmic building blocks to the largest giants in the universe. In this video, we begin with dwarf galaxies, the simplest galaxies we know, before exploring irregular galaxies shaped by powerful gravitational encounters. From there, we move into beautiful spiral galaxies, uncover why their spiral arms aren't permanent structures, and see how barred spiral galaxies use giant stellar bars to fuel star formation and feed supermassive black holes. Next, we explore lenticular galaxies, where star formation has nearly come to an end, before finishing with enormous elliptical galaxies formed through billions of years of galaxy mergers. Along the way, you'll discover how galaxies evolve over cosmic time, why the Milky Way is a barred spiral galaxy, how gravity reshapes entire galaxies, and how the largest galaxies in the universe were built from countless smaller ones. Whether you're fascinated by astronomy, space, or the evolution of the universe, this video will take you on a journey through the incredible diversity of galaxies that fill the cosmos. ⏱ Chapters: [00:00] Dwarf Galaxy [01:02] Irregular Galaxy [02:12] Spiral Galaxy [03:23] Barred Spiral Galaxy [04:29] Lenticular Galaxy [05:24] Elliptical Galaxy
