WorldWide Telescope

Established: April 2, 2002

pg-title_new.pngWorldWide Telescope (WWT) is a virtual telescope to astronomers, a virtual observatory of the Earth to geo-researchers, and an interactive teaching and learning tool to science educators. Since its initial release in late 2006, WWT has become an integral part of many scientists’ research platform and an indispensable curriculum companion for many science teachers worldwide.

The WWT project is a collaborative effort between Microsoft Research and a variety of academic and governmental agencies. Microsoft Research is making WWT available as a free resource to the astronomy and education community with the hope that it will inspire and empower people to explore and understand the universe as never before.

You can install the WWT Windows client on your computer or run the WWT web client. Learn more…
