NASA's image of the day today (click over for larger sizes) is a pretty and cool-looking artist's conception of an early stage in stellar evolution, when an outburst from the young star causes a recrstallization of amorphous silicate particles to forsterite. AKA Mg-rich olivine, AKA peridot.
Imagine the whole region from, say, Mercury to Mars a-swirl with li'l sparkly green gemstones. It's the stuff of happy hallucinations. And apparently it really happened.
