Making Sense of the Universe

Light is the main messenger of the universe. Every star, planet, and galaxy sends out light, and hidden in that light is a record of what the object is made of, how hot it is, and even whether it’s moving toward us or away from us. Matter leaves its “fingerprint” on light through the way atoms absorb and emit energy. By studying these fingerprints—spectra—we can learn about things far beyond our reach. With a spectrometer, we can turn light into data, and data into discoveries about the nature of matter and the motion of the cosmos.
