MACHO Project




A collaboration between American, Australian, and British astronomers to search for MACHOs using a special-purpose charged coupled device camera on the 1.3-meter (50-inch) telescope of the Mount Stromlo and Siding Spring Observatories. It is led by Charles Alcock at the Lawrence Livermore National Laboratory, California. The MACHO team has identified several dozen microlensing events in the Galactic Bulge and Large Magellanic Cloud, including a few which suggest the presence of planets in orbit around distant stars. Immediate notification of possible in-progress lensing events, detected by the MACHO Project, is made available to other interested groups through the Global Microlensing Alert Network (GMAN).
