Answer 1
Brandon Gonzalez
Scientists determine the chemical composition of distant exoplanets primarily through spectroscopy. By analyzing the light that passes through or is emitted by an exoplanet’s atmosphere, scientists can identify specific wavelengths corresponding to various elements and molecules. This method allows them to infer the presence of gases such as hydrogen, helium, water vapor, methane, and carbon dioxide, among others.
