Comet dust particles

Diversity of comet dust particles seen on a small area on one single target of the COSIMA instrument onboard Rosetta. This image section measures 2.5 mm across, with light coming from the right. Examples of a compact particle (a), a shattered cluster (b), a glued cluster (c) and a large rubble pile (d) are seen in this small area.
