NASA | Take a "Swift" Tour of the Andromeda Galaxy

The video explores M31, the nearest large spiral galaxy, highlighting its structure and characteristics. It discusses Swift's ultraviolet observations, revealing differences between the galaxy's bulge and spiral arms. The video also covers the Ring of Fire and satellite galaxies, emphasizing the importance of studying nearby galaxies to understand distant ones. The detailed ultraviolet mosaic provides insights into star formation processes.

What is the approximate distance of M31 from our galaxy?

• 10 million light years

• 5 million light years

• 2.5 million light years

• 1 million light years

What is the main reason visible light does not reveal the full details of M31?

• It is too small

• It is too far away

• It is obscured by dust

• Visible light does not capture all wavelengths

What is the primary characteristic of the spiral arms of M31?

• They are red and smooth

• They contain dense clusters of hot young blue stars

• They are smaller than the galaxy's center

• They are devoid of gas and dust

What is the significance of the giant ring around M31?

• It is a result of interactions with small satellite galaxies

• It is a region with no star formation

• It is the oldest part of the galaxy

• It is a black hole

Why is M32's core bright in the ultraviolet spectrum?

• It likely contains many blue and old stars

• It is a larger galaxy

• It is closer to us than M31

• It contains many young stars
