You're probably wondering what a Pallasite is; well Pallasites are is a type of iron meteorite, quite rare, made out of large olivine crystals in an iron-nickel matrix - and they look just fabulous. Olivine is a a magnesium iron silicate quite common in our planet's subsurface, but which weathers fast when exposed to the surface.
What you are looking at here is a man holding a three foot slab of Pallasite in the Sun - it's not really glowing by itself. I just can't stop wondering where he got it though... probably just found it on the street, or on some field.
