Hypothesis: The newly discovered galaxy is moving away from the Milky Way galaxy, contributing to the observed expansion of the universe. To test this hypothesis, the astronomer can measure the galaxy's redshift using spectroscopy, which will determine the shift in light wavelengths due to the galaxy's motion, thereby indicating whether it is receding from or approaching the Milky Way.
