Hubble's Report on What's Happening to the Galaxies: Hubble Images Episode 12

The video explores the evolution of galaxies, from spiral to elliptical forms, using Hubble's observations. It discusses the characteristics of different galaxy types, including spiral, starburst, lenticular, and elliptical galaxies, and how they evolve over time. The video highlights the role of dust, star formation, and external influences in galaxy evolution, providing examples of various galaxies at different stages.

What has the Hubble Space Telescope significantly contributed to in the past 30 years?

• Exploration of the ocean depths

• Development of new space travel technology

• Knowledge of the universe and galaxies

• Understanding of Earth's atmosphere

Which type of galaxy is characterized by rapid star formation and a red appearance?

• Spiral Galaxy

• Starburst Galaxy

• Lenticular Galaxy

• Elliptical Galaxy

What is a key feature of spiral galaxies that indicates slower star formation?

• Abundance of blue stars

• Presence of red H2 regions

• Symmetrical structure

• Lack of red H2 regions

What happens to a galaxy as it transitions into a lenticular galaxy?

• It gains more gas and dust

• Its spiral arms become more defined

• It becomes a starburst galaxy

• Star formation slows down significantly

What is a characteristic of a lenticular galaxy in its final stages?

• Defined spiral arms

• Rapid star formation

• Lack of gas and dust

• Presence of vibrant blue stars

What is the fate of most stars in an elliptical galaxy?

• They remain young and vibrant

• They become older and redder

• They form new spiral arms

• They become blue giants

What is the expected future of spiral galaxies as the universe ages?

• They will transform into starburst galaxies

• They will evolve into elliptical galaxies

• They will become more common

• They will remain unchanged
