Pluto may have been demoted from planet to “dwarf planet,” but it’s far from boring. In this talk, we’ll unpack the 2006 decision by the International Astronomical Union—what criteria led to Pluto’s reclassification, and why the debate still rages today. Then we’ll fast forward to July 2015, when NASA’s New Horizons spacecraft flew past Pluto, sending home breathtaking images of mountains, canyons, and heart‑shaped ice plains. You’ll discover how Sputnik Planitia’s nitrogen glaciers flow across the surface, how towering water‑ice mountains defy expectations, and why cryovolcanism may still be active. Finally, we’ll put Pluto’s ice to the test: side‑by‑side comparisons with Earth’s glaciers will challenge you to spot the differences in composition, temperature, and behavior. By the end, you’ll see why Pluto remains one of the most fascinating—and surprisingly familiar—worlds in our solar system.
