Roman Space Telescope Science Platform Will Open New Frontiers in Space Science

April 16, 2026

$Illustration shows four people at work within the outline of a large cloud. At center is a woman with a ponytail and dark skin whose hand is raised and close to the Roman Space Telescope body floating in space next to small white stars. The words, Roman Research Nexus, arc above the pair under the cloud outline. To her left are two other people, one with darker skin who is wearing headphones and writing and another with lighter skin, also with headphones, at a laptop. At right is a man with glasses, short wavy brown hair and light skin who is looking left, toward the telescope. In the background within the cloud shape, there are zeros and ones falling in the left third. At center is part of an outline of Roman’s camera’s field of view, and at right are representations of charts. Above the cloud is a darker background with simpler dark blue shapes. From left to right, they show a sphere following a path, a large spiral galaxy, a large ringed planet, and an object with diffraction spikes.$
