Something About Pluto No Longer Makes Sense

Pluto, Planet, New Horizons Is Pluto really a dead, frozen rock, or one of the most geologically active worlds in the solar system? In 2006, astronomers voted to strip Pluto of its planet status, calling it too small, too cold, and too far out to count. Nine years later, NASA's New Horizons spacecraft flew past Pluto and sent back images that upended everything scientists thought they knew. This video breaks down exactly why Pluto was demoted to a dwarf planet, and what New Horizons discovered on July 14, 2015, and why Pluto's giant heart-shaped region, Sputnik Planitia, has zero impact craters — proof its surface is actively resurfacing itself in real time. You'll see the nitrogen ice glaciers flowing across Pluto, the mysterious cryovolcanoes Wright Mons and Piccard Mons, and the leading scientific theory for why Pluto may be hiding a 100-kilometer-deep liquid ocean under its icy crust. If you've ever wondered why Pluto isn't a planet anymore, how old Pluto's surface really is, or whether Pluto has an ocean, this video has the clearest explanation available, backed by NASA's New Horizons mission data.
