Microscopic view of a meteoroid's trail (5 hundredths of an inch long) in aerogel, captured by the EURECA spacecraft. The trail, resembling a tiny carrot, shows the path of a dust particle (about a thousandth of an inch in diameter) possibly originating from a comet, offering insights into the early Solar System.
