Roman Space Telescope Mission
When it launches in the mid-2020s on a mission planned for five years, Roman will survey wide areas of space with a field of view much larger than the Hubble Space Telescope or the James Webb Space Telescope. Those predecessors take detailed views of smaller areas of space, more like a zoomed-in view to Roman’s panoramic.
Roman will observe billions of galaxies, detailing supernovae and other cosmic phenomena. The data will fuel discoveries on dark energy and dark matter, two mysteries of the universe that science cannot fully explain. The telescope will also study exoplanets – planets outside of our solar system – with unprecedented detail. Roman will monitor 100 million stars for hundreds of days and is expected to discover about 2,500 new planets. Included in that number are rocky planets in regions that may support the existence of liquid water.
