WorldWide Telescope (WWT) is a tool for showcasing astronomical data and knowledge. It’s not a physical telescope — it’s a suite of free and open source software and data sets that combine to create stunning scientific visualizations and stories. The WWT ecosystem includes a Windows application, an interactive web app, and toolkits for Python and TypeScript/JavaScript.
WWT is a fiscally sponsored project of NumFOCUS, a nonprofit dedicated to supporting the open-source scientific computing community. If you like WWT and want to support our mission, please consider making a tax-deductible donation to support our efforts. NumFOCUS is a 501(c)(3) non-profit charity in the United States; as such, donations to NumFOCUS are tax-deductible as allowed by law. As with any donation, you should consult with your personal tax adviser or the IRS about your particular tax situation.
The American Astronomical Society (AAS) is a founding sponsor of the WorldWide Telescope project and assisted with its transition from a commercial to an Open Source effort. Significant financial, administrative, and programmatic support enabled the fully open realization of this amazing resource, which continues to be utilized throughout the astronomical community for a variety of educational and research-related efforts.
