Rogue Planets Revealed: Roman Space Telescope and the Hunt for Invisible Worlds

Prepare for a revolution in exoplanet science with the Nancy Grace Roman Space Telescope, a next-generation mission designed to uncover thousands of hidden planets across the Milky Way. Using gravitational microlensing, Roman will detect planets not by their light, but by how their mass bends and magnifies starlight, revealing worlds that are otherwise completely invisible.This episode explores how Roman’s Galactic Bulge Time-Domain Survey will uncover rogue planets—free-floating worlds with no host stars—as well as distant, cold planets similar in mass to Earth. These discoveries build on evidence that such starless planets may outnumber stars in our galaxy.We also examine the supporting role of the Euclid telescope, which can refine measurements and improve detection accuracy. Together, these missions aim to create the most complete statistical census of planetary systems ever attempted, helping scientists understand how planets form, evolve, and disperse across the galaxy.Timestamps:00:00 Introduction: The hidden population of planets in the Milky Way02:30 What is the Nancy Grace Roman Space Telescope?
