Why Venus Could Doom 'Habitable' Exoplanets

The video explores the concept of Earth twins, focusing on exoplanets similar to Earth that may harbor life. It highlights Venus as an example of an Earth twin that underwent drastic climate changes, leading to its current inhospitable state. The Venus Zone is introduced as a region where planets could start habitable but become uninhabitable due to a runaway greenhouse effect. The video discusses the importance of understanding the Venus Zone for studying exoplanets and the role of future research, including the James Webb Space Telescope, in advancing our knowledge of planetary habitability.

What factors contributed to Venus undergoing a runaway greenhouse effect?

Why is the study of Venus important for understanding habitability on other planets?
