Welcome to the WorldWide Telescope Contributor Hub!

WorldWide Telescope (WWT) is a free, open-source tool for visually exploring humanity’s scientific understanding of the Universe. WWT is primarily a website that allows anyone to interactively explore terabytes of astronomical data in a seamlessly integrated 4D simulation of the known universe. But the WWT software ecosystem also includes a Windows application that can power planetariums, a cloud-based web service for discovering and sharing astronomical data, and a Python module allowing users to write their own software to control and extend all of these systems.

WorldWide Telescope 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, 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.
