In the cold nurseries between stars, billions of light-years from any human hand, the chemistry of life itself is being assembled in slow, invisible processes. Astrochemists on Earth have learned to listen for the radio whispers of spinning molecules in places like the Orion Kleinmann-Low nebula, 1,300 light-years away, using instruments like ALMA to decode the conditions of star birth with ever-finer precision. What emerges from this patient work is not only a map of distant chemistry, but a deeper understanding of how the universe prepares the ingredients for worlds like ours — and the quiet
