Use the scenario to answer the question.
An astronomer discovers a new galaxy using a telescope. The astronomer wants to investigate how the
galaxy is moving relative to the Milky Way galaxy.
In one or two sentences, make a hypothesis about the movement of the galaxy and explain at least one way
to test the hypothesis.
(2 points)
Hypothesis: The new galaxy is moving away from the Milky Way galaxy.
One way to test this hypothesis is to measure the redshift of the light emitted by the galaxy. If the light is found to be redshifted, it suggests that the galaxy is moving away from us, supporting the hypothesis.
