Since Pluto lost its planet status in 2006, some scientists believe a mysterious ninth planet may exist in our solar system, and a new powerful telescope, the Vera Rubin Observatory, set to begin its mission in June 2025, could help uncover its existence by scanning the southern hemisphere sky and cataloging billions of cosmic objects, potentially revealing new trans-Neptunian objects and confirming or denying the planet's presence. #PlanetNine #Astronomy #SpaceExploration #CL #US #JP #AU #DE #TW
