Could Water Survive on the Closest Exoplanet?

The video discusses exoplanets, focusing on HAT-P-26b and Proxima Centauri b. HAT-P-26b, a Neptune-sized planet, has a unique atmosphere with low metallicity, suggesting it formed closer to its star. Proxima Centauri b, located in the habitable zone, may support liquid water, making it a candidate for alien life exploration. The video also highlights the challenges posed by its parent star's radiation. The episode concludes with acknowledgments to SciShow Space supporters.
