COVER Einstein watches in surprise as a universe expands exponentially, its galaxies rushing apart ever faster. Evidence for an accelerating universe, the Breakthrough of the Year for 1998, resurrects Einstein's discarded idea of an energy called lambda, or l, which counteracts gravity and pushes space apart. See the Breakthrough of the Year section beginning on page 2156 and the Editorial on page 2193. [Illustration: John Kascht]
