In the previous video, we saw how the atmosphere of an exoplanet can be observed. These observations naturally inform us about the physics and chemistry of the atmosphere, but what else can we deduce from this?
The astrophysicist Pascal Tremblin answers this question in two ways: planetary migration and the notion of habitability. This video will thus help you identify different aspects of what is to be gained from studying planetary atmospheres.
For more information: Without the atmosphere, there would certainly be no life on Earth. Studying it is highly complex but crucial to understanding the Earth’s climate. See how the Earth’s climate works with this animation developed by CNRS.
