Pluto's Runaway Atmosphere, and Earth's 'Cousin'

The video discusses the New Horizons mission's findings on Pluto, revealing unexpected geological activity and atmospheric changes. It highlights the discovery of flowing nitrogen ice and a rapidly thinning atmosphere. The video also covers Kepler's identification of new exoplanets, including Kepler 452B, which shares similarities with Earth but has significant differences. The video concludes with a call to support SciShow on Patreon.
