When you look at starlight through a prism, the light separates into a rainbow of color, but some of the colors are missing. This phenomenon might help us one day discover alien life on another planet. Find out how here:
This method of seeing a planet’s spectrum through starlight is our biggest key to the search for life. As bigger and better telescopes like the recently launched JWST move us toward the future of looking at habitable and inhabited planets, exoplanet spectroscopy will be our eyes — and someday, those eyes will make the discovery of a lifetime.
