NASA | JWST Feature - Colliding Galaxies

The video explores the formation and evolution of galaxies, highlighting how they are the universe's building blocks. It discusses the ongoing process of galaxy construction through interactions and mergers, affecting their structure and chemical makeup. The video details the Milky Way's interaction with the Sagittarius Dwarf Galaxy and the future collision with the Andromeda Galaxy. It concludes with insights into how deep space surveys, like those by the James Webb Space Telescope, will enhance our understanding of galaxy evolution.

What are galaxies primarily composed of?

• Stars, gas, and dark matter

• Only stars

• Just gas clouds

• Only dark matter

How do gravitational tides affect galaxies during interactions?

• They make galaxies spin faster

• They distort galaxy shapes and create star streams

• They have no effect on galaxies

• They cause galaxies to shrink

What significant event involving the Sagittarius Dwarf Elliptical galaxy was discovered in 1994?

• It was merging with the Andromeda Galaxy

• It was colliding with another dwarf galaxy

• It was forming new stars rapidly

• It was being torn apart by the Milky Way

What is the expected outcome of the Milky Way's interaction with the Andromeda Galaxy?

• The Milky Way will be destroyed

• They will pass by each other without any effect

• They will merge into a new galaxy

• Andromeda will be ejected into intergalactic space

What role will the James Webb Space Telescope play in understanding galaxies?

• It will only study the Milky Way

• It will map only the Andromeda Galaxy

• It will capture the evolution of galaxies over time

• It will focus on black holes
