About
How can a tiny change inside a hydrogen atom reveal the structure of an entire galaxy? We explore the 21-centimeter hydrogen line, the radio signal that lets astronomers peer through cosmic dust and map the Milky Way. Discover how this natural beacon helps probe the early universe—and why it has become a reference point in the search for extraterrestrial intelligence.
