Question

The Andromeda Galaxy is the most distant celestial object that can be seen with the

unaided eye. How far away from the Milky Way is the Andromeda Galaxy located? Hint: Press

the Info button in the selection label.

a. 9.2 million light years

b. 2.5 million light years

c. 9.2 billion light years

d. 2.5 billion light years

Use Hubble's Law to calculate the recessional velocity of the Virgo cluster of

galaxies. How fast are these galaxies receding away from us?

a. 1240 km/sec

b. 2480 km/sec

c. 124 km/sec

Using the formula z=v/c, what is the redshift of the galaxies in the Virgo cluster?

a. 0.04

b. 0.004

c. 0.0004

What is the calculated recessional velocity of the Abell cluster of galaxies?

a. 24,000 km/sec

b. 2,400 km/sec

c. 4,200 km/sec

d. 42,000 km/sec

For the Abell cluster of galaxies z = 0.14, and for the Virgo cluster z = 0.004. What

can be said about the relationship between distance and redshift from this small sample of redshifts?

a. Smaller redshift values correspond to greater distance.

b. Larger redshift values correspond to less distance.

c. Larger redshift values correspond to greater distance.

d. There is no relationship between redshift and distance

Explanation / Answer

they both are located at a distance of 2.5 million light years. this galaxy is the nearest galaxy to Earth excluding the small companion galaxies. this is a spiral galaxy and can be seen with naked eye. this is confirmed by Edwin Hubble.
