Question

this image of a tiny fraction of the night sky was taken through a powerful telescope. many of the objects seen in the image are galaxies similar to the milky way.

telescopes have taken many images like this one, but of different fractions of the night sky. what do these images suggest?
a. the milky way is the largest galaxy in the universe.
b. there are no other galaxies in the universe.
c. each galaxy contains an equal number of stars.
d. there are many other galaxies in the universe.

Explanation:

The image shows a small section of the night sky filled with numerous galaxies similar to the Milky Way. Repeating this observation across different sky fractions confirms the Universe contains countless other galaxies, while the other options are incorrect: the Milky Way is not the largest galaxy, we clearly see other galaxies here, and galaxies vary greatly in star count.

Answer:

D. There are many other galaxies in the Universe.
