A comet born in a colder, dimmer corner of the galaxy has arrived in our solar system carrying chemical evidence that the universe does not forge all worlds from the same conditions. Catalogued as 3I/Atlas, this ancient traveler holds water rich in deuterium — a heavier form of hydrogen — at concentrations thirty to forty times greater than anything found in our own cosmic neighborhood. Its composition is not an anomaly but a record, a faithful inscription of the frigid, low-radiation environment where it was made. In reading this visitor's chemistry, astronomers are confronted with a humbling
