Explanation:
Detailed explanation-1: -Spectrographs collect data that tell scientists how much light comes out at each wavelength. These data reveal important details about the makeup of atmospheres on exoplanets, the compositions of stars and nebulas, the motion of galaxies and more.
Detailed explanation-2: -The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy. Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object’s spectrum, they can determine its composition based on these wavelengths.
