Announcing the Opening of the Roman Research Nexus

12 January 2026

We are pleased to announce that the Roman Research Nexus is now available for use! 

The Nancy Grace Roman Space Telescope will deliver an estimated 20 PB of data in its primary 5-year mission. In just one month, Roman will generate roughly twice the data volume produced by Hubble over 30 years. The Roman Research Nexus will provide the science community with a cloud-based science platform to efficiently access, explore, and analyze Roman's large volume of data. 

The Nexus cloud-based scientific computing environment includes pre-installed software, Jupyter notebook tutorials, access to simulated datasets, team workspaces, and real-time collaboration tools.  Once Roman science operations start, all Roman data will be accessible through the Nexus.

Check out the Nexus now to start exploring existing simulated Roman datasets, quickly simulate your own Roman data using pre-installed simulation tools and pedagogical notebooks, and get familiar with Roman's data formats. All you need is a myST account to login and get started.

The Roman Research Nexus is developed and provided to the community by the Space Telescope Science Institute, in collaboration with Roman Mission Partners.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
