WorldWide Telescope (WWT)
The WorldWide Telescope (WWT) is a free, open-source tool for exploring our knowledge of the universe. It provides planetarium-like views of the sky, as well as dynamic images of planets and other astronomical objects. The project enables users to incorporate images and video into scripts for custom “tours”, for use in classrooms, planetariums, museums, and other multimedia displays. WWT is a project of the American Astronomical Society (AAS), with scientific consultants from universities around the world, including the Center for Astrophysics | Harvard & Smithsonian. The WWT Ambassadors are scientists and science educators at CfA who use the WWT in public science outreach and education. WWT is both available as a web browser application and a desktop program for Windows computers.
