The Mysteries of Pluto

This documentary journeys to Pluto, the small icy world 3.5 billion miles from the Sun, and unpacks what the New Horizons flyby revealed about it. It explores Pluto's thin atmosphere, possible subsurface ocean, ice mountains and nitrogen glaciers, and revisits the debate that demoted it to dwarf planet in 2006. The film keeps the science clear, separating confirmed discoveries from open questions about this distant frontier. It is a rewarding watch for anyone drawn to the mysteries of the outer solar system. Free to watch in HD on Dr Documentary.
