Overview

• Nearly 4 million simulated images depict the cosmos as seen by NASA’s Roman Space Telescope and the Vera C. Rubin Observatory.
• The simulation campaign, led by Duke University, is part of the OpenUniverse project.
• The Argonne National Laboratory's Theta supercomputer completed the simulation in nine days, a task that would have taken 300 years on a standard laptop.
• Simulations help scientists understand instrument performance and prepare for analyzing real data from the telescopes.
• The project involves collaboration between NASA, DOE, Argonne, SLAC, and other institutions.
