One of the featured articles in AccessScience this month is Accelerating universe, by Robert P. Kirshner, Professor, Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts. It explains how astronomers used evidence from exploding stars to show that the expansion of the universe is not slowing down, as would be expected from the pull of gravity on matter in the universe, but is instead speeding up. Learn about the history of this understanding, and how type 1a supernovae are used as "standard candles" to track expansion.
