This carrot-shaped track is actually little more than 5 hundredthsof an inch long.It is the trail of a meteroid through the high-tec substance aerogelexposed to space by the shuttle launche EURECA(European Recoverable Carrier) spacecraft Like those i the ongoing Leonid meteor shower, thismeteoroid is about a thousandth of an inch in diameter.It is visible where it came to rest, justbeyond the tip of the carrot at the far right.Chemical analyses o interplanetary dust particles similarto this one suggest that some of them may b bitsof comets and thus represent samples of material fro theearly stages of the formation of the Solar System.
