A team of researchers affiliated with several institutions in Spain and one in France has built what they call their Stardust machine—a device that mimics the activity around a red giant where real stardust forms. In their paper published in the journal Nature Astronomy, the group describes their new machine and what it showed them about the means by which stardust forms naturally. Michael Gatchell, with Stockholm University, has published a News & Views piece discussing the work in the same journal issue.
