Las Cumbres Observatory Global Telescope Network (LCOGTN) is a privately funded, nonprofit organization that is creating a cutting edge science program paired with a innovative education program. When it is complete, the Network will use the internet to link robotic telescopes at the Las Cumbres Observatory in Santa Barbara, CA with others around the world. Currently, two telescopes are online from Haleakala, Maui and Sliding Spring Observatory in New South Wales, Australia. Three telescope deployments are scheduled for 2008, and three more for 2009.

Eventually the education network will consist of about 28 0.4-meter telescopes, and the science network will consist of about 28 one-meter telescopes. Two two-meter telescopes will be available for scientific follow-up. The telescopes within the network will be able to hand off observations from one site to the next, acting as an unblinking eye on the sky for 24 hours a day, every day.

Most objects in the universe vary on some time scale, ranging from fractions of a second to several days, months, years, or millennia. Astronomers have long dreamed of being able to take long term observations of transients, such as extrasolar planets, supernovae, and variable stars. The Las Cumbres Network promises to make the dream a reality.
