The Web manifestation of WWT has gone through several stages of evolution. These stages include a Silverlight version and the
<canvas>-based “HTML5” version. This documentation describes the “WebGL” version, which is the latest and, we hope, final version of the WWT web engine. We won’t intentionally break the older versions, but there are no guarantees that they will continue functioning going forward.
The AAS WorldWide Telescope system is a .NET Foundation project managed by the non-profit American Astronomical Society (AAS). Work on WWT has been supported by the AAS, the US National Science Foundation (grants 1550701 and 1642446), the Gordon and Betty Moore Foundation, and Microsoft.
