Abstract :
Supernovae are the best tools astronomers have to precisely measure large distances, and therefore to track the expansion history of the Universe. Observations of distant supernovae have surprisingly indicated that the Universe is not decelerating under the gravitational pressure of the matter within it, but rather accelerating - pulled apart by some pervasive smooth tension, or "dark energy".
