Chris inquires: "Do meteorites 'glow' under a UV light?"
I don't know whether meteorites glow under a UV light but I do know
that meteorites glow, i.e. some meteoritic minerals emit light when
exposed to an electrical discharge => luminescence
Herschel was one of the first to observe thermoluminescence (TL),
which is a result of heat stimulation.
Samples irradiated by an electron beam can glow with what is called cathodoluminescence (CL).
A thermoluminescent mineral is usually cathodoluminescent as well.
