How do Astronomers Determine Exoplanet Atmospheres

Although most exoplanets are too distant to be directly imaged, detailed studies have been made of their size, composition, and even atmospheric makeup - but how?

By observing periodic variations in the parent star's brightness and color, astronomers can indirectly determine an exoplanet's distance from its star, its size, and its mass. But to truly understand an exoplanet astronomers must study its atmosphere, and they do so by splitting apart the parent star's light during a planetary transit.

Excellently prodcued video, Got a physics presentation to write on this topic and you've helped me out loads.

The fact that we can determine the exact chemicals in a planets atmosphere billions of light years away using math is just mind blowing 🤯

Very good explanations and visualizations helped me out a great deal.

A technique called transmission spectroscopy is used to detect the atmospheres of exoplanets
