Mama, Where Do Galaxies Come From?

The video explores the evolution and study of galaxies, focusing on the role of ultraviolet (UV) light in understanding their life cycles. It highlights the contributions of the Galaxy Evolution Explorer (Galex) in capturing UV light to study galaxies' evolution from blue spirals to red ellipticals. The video also discusses significant discoveries made by Galex, such as the formation of stars in unexpected regions and the reanimation of dead galaxies by acquiring new gas. These findings have provided valuable insights into the life and evolution of galaxies.

Describe the hypothesis regarding the evolution of galaxies from blue spirals to red ellipticals.

What evidence did Galex provide to support the hypothesis about teenage galaxies?

How did Galex contribute to our understanding of 'dead' galaxies?
