@worldspaceobservatory: 👇👇Largest Ring Exoplanet In The Universe 420 light-years away, a young star hides a giant called J1407b—a world with the largest known ring system in the universe. Over 30 massive rings stretch more than 90 million kilometers wide, dwarfing Saturn’s by 200×. Astronomers think those dark gaps between the rings could be new moons forming right now. If J1407b replaced Saturn in our sky, its rings would dominate the night—bigger and brighter than the full Moon. A glimpse of how wild young planetary systems can be. #planets #Astronomy #astrophysics #space
