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

During the 1970s, astronomer became aware of a massive radio source at the center of our galaxy that they later realized was a Supermassive Black Hole (SMBH) – which has since been named Sagittarius A*.
