Measurements of pulsar acceleration reveal Milky Way's dark side
It is well known that the expansion of the universe is accelerating due to a mysterious dark energy. Within galaxies, stars also experience an acceleration, though this is due to some combination of dark matter and the stellar density. In a new study, researchers have now obtained the first direct measurement of the average acceleration taking place within our home galaxy, the Milky Way.
