The Space Observatory That Could Explain Dark Energy

NASA is preparing for the launch of the Nancy Grace Roman Space Telescope, a next-generation observatory scheduled for September 2026.

Equipped with a 2.4-meter mirror and a field of view far larger than Hubble’s, the mission will study dark energy, map galaxy evolution, and search for thousands of exoplanets from its position at the Lagrange L2 point.

Featuring advanced wide-field imaging and a cutting-edge coronagraph, the telescope is ahead of schedule and within budget. Once operational, Roman will work alongside other major observatories to deliver massive new datasets for astronomers around the world.
