From the cold silence of the early galaxy, a traveler 11 billion years old has passed through our solar neighborhood carrying chemical memories of a cosmos we have never directly seen. Comet 3I/Atlas, only the third confirmed interstellar visitor in recorded astronomy, bears unusually high concentrations of deuterium — a molecular signature pointing to a birth in profound isolation, far from the warmth of neighboring stars. Scientists at the University of Michigan, using the ALMA observatory in Chile, have read that signature as a rare dispatch from the conditions that shaped planets in the un
