Ep 4. Secret History Of Pluto

In this episode of How the Universe Works, entitled "Secret History of Pluto," viewers will uncover the mysterious history of the once-ninth planet in our solar system. Scientists have long been fascinated by the small, icy world that orbits at the edge of our cosmic neighborhood, and recent discoveries have revealed surprising details about its past.

The episode begins by exploring how Pluto was discovered in 1930 by American astronomer Clyde Tombaugh. Initially considered the ninth planet, Pluto's unique orbit and small size eventually led to its reclassification as a dwarf planet in 2006. However, as the episode shows, Pluto remains an important object of study for scientists seeking to understand the formation and evolution of our solar system.

Through a mix of stunning CGI animations and interviews with leading scientists, "Secret History of Pluto" delves into the planet's past. For example, viewers will learn about the theory that Pluto may have formed in a different part of the solar system before being flung outward by the gravity of nearby planets. They will also discover how Pluto's surface was shaped by processes such as tectonic activity and volcanic eruptions, which were only recently detected by NASA's New Horizons spacecraft.

Perhaps most intriguingly, the episode reveals that Pluto may harbor liquid oceans beneath its icy crust. This possibility has excited scientists, as it suggests that Pluto could potentially host life in some form. The episode explores the conditions that would be necessary for such life to exist, as well as the challenges of exploring a world as distant and hostile as Pluto.

Throughout "Secret History of Pluto," viewers will gain a new appreciation for this enigmatic and fascinating world. From its discovery to its reclassification as a dwarf planet, Pluto has held an important place in our understanding of the solar system. As scientists continue to study its secrets, we may yet uncover new insights into the origins and fate of our cosmic home.
