The source of a mysterious microwave glow detected across our galaxy eluded astronomers for decades. But now a crack team has finally pinpointed the source: nanoscopic particles of crystalline carbon, otherwise known as diamond dust. There are several environments across the Milky Way that produce a faint glow known as anomalous microwave emission (AME). Scientists
