The Spitzer Space Telescope has, for the first time, detected tiny quartz-like crystals sprinkled in young planetary systems. This surprises astronomers, because these crystals, which are types of silica minerals called cristobalite and tridymite, require flash heating events, such as shock waves, to order to form. So what is going on in these planetary [...]

Fraser. This is interesting. When cosmic rays strike quartz crystals, the Bremstrahlung radiation emitted is mostly in the form of....microwaves. So galaxies with billions of stars and planetary systems ought to be emitting some microwave backgrounds, but not blackbody.
