Aerogel is the world’s lightest solid — and also the most porous. I’ve got a story on Wired News this morning that explains all about this really cool material, how it was used in NASA/JPL’s recent Stardust mission, and how some companies are commercializing the stuff. This story was really fun to write, not least because of the nifty aerogel samples I got to handle.
