MACHO Project

(survey searching out microlensing that could indicate a MACHO)

The MACHO Project was a mid-1990s survey searching for gravitational microlensing events that could indicate MACHOs, i.e., dark matter in the form of brown dwarfs or field planets. The project used a 1.27-meter telescope at Mount Stromlo Observatory, Australia to view the Large Magellanic Cloud and Small Magellanic Cloud, targeting dark matter in front of the two which would constitute part of the Milky Way's galactic halo. The project was begun in 1992 and found some microlensing candidates and also recorded other interesting transients such as novae, and variable star events. Similar projects have been EROS and OGLE.
