Roman for Scientists
Expanding our view ... to a panoramic vista 200 times larger than Hubble’s infrared view.
The Nancy Grace Roman Space Telescope is a Hubble-sized telescope that will revolutionize astronomy by building on the science discoveries and technological leaps of the Hubble and James Webb space telescopes. The Roman Project is currently planning for observatory launch in late 2026.
Roman will provide a panoramic field of view that is 200 times greater than Hubble's infrared view, leading to the first wide-field maps of the universe at space-based resolution. Roman will combine the power of imaging and spectroscopy in synergy with other observatories to gain fresh insights into the universe through focused surveys and General Astrophysics observations.
Using a wide field instrument, Roman will survey billions of galaxies and catch the light of stellar explosions in a quest to solve the mystery of dark energy, which is causing the universe’s expansion to speed up. Roman’s scans of the sky will uncover thousands of exoplanets beyond our solar system, including types of planets never surveyed before.
Beyond these two primary goals, Roman will probe a range of additional astrophysical and planetary science topics such as stars in neighboring galaxies, supermassive black holes in faraway galaxies, cosmic nurseries where stars and planets come to life, and small bodies in our solar system.
