pywwt: The AAS WorldWide Telescope from Python/Jupyter

🚀🚀 Click here to try out pywwt in the cloud! 🚀🚀

Note: our cloud servers usually start up quickly, but if they were recently updated you may have to wait a few minutes for the backing software images to be rebuilt.


The pywwt package is the official toolkit for accessing the AAS WorldWide Telescope (WWT) from Python. WWT is a free, open-source tool for visually exploring humanity’s scientific understanding of the Universe. It includes a sophisticated 4D WebGL rendering engine and a cloud-based web service for sharing and visualizing terabytes of astronomical data. WWT is brought to you by the non-profit American Astronomical Society (AAS), the major organization of professional astronomers in North America, and the .NET Foundation.

With pywwt you can:

  • Visualize and explore astronomical data interactively in the Jupyter and JupyterLab environments through an HTML widget
  • Do the same in standalone applications with a Qt widget
  • Load data from common astronomical data formats (e.g. AstroPy tables) into WWT
  • Control a running instance of the WWT Windows application

The full documentation, including installation instructions, can be found at
