When You Wish Upon a Star
Stardust, a NASA mission being managed by the Jet Propulsion Laboratory, will fly by comet Wild-2 in 2004. Passing through the comet's coma (the gas cloud surrounding the comet's head), the spacecraft will suck up some cometary particles from the coma as it passes (at 14,000 miles per hour!) and return it to Earth in 2006 for detailed analysis.

The sample materials will be captured in Aerogel, the lowest density solid material ever created. An absolutely incredible substance (I've seen it), it's often referred to as "solid smoke". And that's exactly what it looks like, too.
