Hypothesis: The newly discovered galaxy is moving away from the Milky Way galaxy due to the expansion of the universe.
One way to test this hypothesis would be to measure the galaxy's redshift using a spectrometer. If the galaxy's light is consistently shifted towards longer wavelengths, it would indicate that the galaxy is moving away from us, supporting the hypothesis.
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.
