NASA's Roman Mission Simulates Universe Using Supercomputers
Researchers create 4 million images to preview observations from upcoming space telescopes, aiding in the study of dark energy and the universe's evolution.
- 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.
