K2-18b: The Exoplanet That Could Have Life | What We Know So Far
Показать описание
In this video, I explore the exciting news about K2-18b, an exoplanet that could have life. K2-18b is a mini-Neptune that orbits a cool dwarf star in the habitable zone, meaning that it could have liquid water on its surface. NASA’s James Webb Space Telescope recently detected methane and carbon dioxide in its atmosphere, which are possible signs of biological activity. Could K2-18b be a second Earth? Or a Hycean world with a water ocean and a hydrogen-rich atmosphere? Watch this video to find out!
