Spectroscopy with Webb

Spectroscopy with Webb
Spectroscopy is a tool to better understand the physics of objects in space. Like a prism splits white light from the Sun into its colour components (like a rainbow), the James Webb Space Telescope’s spectrographs will split infrared light into its many wavelengths. This will provide detailed information about an object, such as how a galaxy moves or what molecules are present in an exoplanet’s atmosphere.
