Seven internationally famous specks of dust

This August, a consortium of 65 scientists announced in the journal Science that they have so far found seven probable but not confirmed interstellar dust specks in a collector returned to Earth by the Stardust spacecraft in 2006. Undergraduate students at Washington University in St. Louis found three of the seven specks of dust.
