A proposed see-it-all telescope has found a home, but backers still need $300 million to build it.
The Large Synoptic Survey Telescope (LSST) would detect menacing asteroids and galaxies and probe space-stretching dark energy. Last week, a siting committee decided that LSST should perch atop Cerro Pachón, a Chilean peak that is already home to two other big telescopes. The site beat out one with poor infrastructure in Baja California, Mexico. Project leader J. Anthony Tyson of the University of California, Davis, hopes that the National Science Foundation will pony up enough to begin construction in 2009 on the telescope, whose novel design features a digital camera with 3 billion pixels.
