A distant star is between our Milky Way galaxy and the Andromeda galaxy. It emits mostly yellow light as it approaches the Andromeda galaxy. How would the color appear to an alien in the Andromeda galaxy?

• The star’s light would be shifted closer to the color red

• The star’s light would be shifted closer to the color blue

• The star’s light would not appear to be different

• It depends on how fast the star is traveling

What causes the redshift observed in astronomy?

• The decrease in the speed of light from distant galaxies

• The increase in the speed of light from distant galaxies

• The movement of galaxies away from us, stretching the light waves

• The movement of galaxies towards us, compressing the light waves

Why is the light from distant galaxies red-shifted?

• They produce more red light than nearby galaxies

• They are moving away from us

• The longer wavelengths are filtered out more by dust

• They are moving toward us
