The Roman Research Nexus is a JupyterHub environment developed and provided by the Space Telescope Science Institute (STScI). The Nexus offers Roman software, analysis tools, simulated data, and cloud-based compute resources, and will provide access to Roman mission data as they become available.

Early Access allows users to build and test workflows, work with simulated datasets, and become familiar with the same tools that will be used with Roman data during operations.

The platform is designed to support collaborative, team-based research. Users have access to shared team spaces, curated software environments, and real-time collaboration servers, enabling teams to work together seamlessly within the same cloud platform.

As capabilities expand, the Nexus will remain the central cloud workspace for the Roman science community throughout Roman operations.
