Astronomers estimate the mass of the stars in a certain galaxy to be about 3.040 kg, and the total mass of this galaxy to be about 1.241 kg. The amount of the galaxy's mass is made up of dark matter is percent
Through the use of various measurement techniques, it has been found that most galaxies are rapidly receding (moving away) from the Milky Way, and in fact, galaxies in distant superclusters are moving away from us more rapidly than nearby superclusters.  This recessional motion is present throughout the Universe and is called the
We know that dark matter must exist in galaxies. If not, many of the stars in a galaxy would ... a.Expand and go supernova due to the expansion of the Universe   b.Fly away from the galaxy because the stars’ velocities are so large, and the galaxy would not have enough gravity to hold onto them   c.Orbit the center of the galaxy normally   d.Spiral in toward the center of the galaxy because most of the galaxy’s mass would be toward the center
