It reads the barcode of light, naming atoms you'll never touch from across the galaxy.
means A scientific instrument that measures the wavelengths and intensities of light or other radiation, splitting it into a spectrum to reveal what something is made of.
from A marriage of two halves: "spectro-" from Latin "spectrum," meaning an appearance or apparition (from "specere," to look), and "-meter" from Greek "metron," a measure. So at root it is a "measurer of appearances" — fitting for a device that pins down the ghostly fingerprints of light. The compound is a 19th-century coinage, born alongside the era's hunger to quantify the once-untouchable.
