Peering Into the Milky Way's Far Side, Roman Could Unveil 100,000 Worlds

Scientists expect the mission to reveal around 100,000 worlds—a staggering leap compared to the nearly 6,300 found so far thanks to NASA missions working in tandem with other observatories. And Roman will primarily find them in underexplored regions of the Milky Way.
