The Mysterious Ridges Near Pluto's Heart

The video explores Pluto's unique geological features, focusing on the heart-shaped Tomba Regio and the craterless Sputnik Planicia. It delves into the mysterious washboard and fluted terrains, proposing a hypothesis involving geological activity and nitrogen ice sublimation. Additionally, the video discusses the potential discovery of a Super Earth orbiting Barnard Star, highlighting the challenges and opportunities in exoplanet research.
