Larry Nittler provided a “Perspectives” piece for the 7 May issue of Science, entitled “Cometary Dust in the Laboratory,” that comments on recent research results on the early solar system obtained by American and French research teams. Both teams took advantage of the availability of relatively less studied primitive materials returned by the Stardust mission to comet Wild 2 and from Antarctic micrometeorites.
