    Astronomers Just Cracked The Cosmic Mystery of Anomalous Microwave Glow in Our Galaxy



    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.

    Just read an article on that, and nice that one other mystery in the universe has got some closure.

    The latest discovery owes more to chance than design. Jane Greaves, an astronomer at Cardiff University, was observing belts of gas and dust around 14 massive young stars in the hope of catching planets in the act of formation. But when she looked over her data she found a spike in microwaves coming from the dusty disc around one of the stars.

    Greaves discussed the spike with her colleague Anna Scaife at Manchester University who, it turned out, had seen similar peaks in microwaves coming from two other stars. It so happened that the three stars are the only ones known to be circled by discs of diamond dust. “I said: ‘We’ve got three here and they are the only three stars anywhere known to have these diamonds around them,’” said Greaves. “That was quite a shock.”
