... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.€а Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.€а €аAlbert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

In 1990, Duncan Steel, then of the Uni. of Adelaide, commenced the Anglo-Australian Near-Earth Asteroid Survey. This project took advantage of the photographic work being undertaken at the 1.2-m U.K. Schmidt Telescope of the Anglo-Australian Observatory. Since the U.K. Schmidt had commenced its photographic sky surveys in 1973, many comets had been found, but few NEAs. ... The status of the AANEAS and other U. K. Schmidt NEA discoveries can be found here. ... Siding Spring Survey Main Page . ...
