| We'll check in with researchers on the Stardust probe, which captured dust from comet Wild-2 in 2004. Recently, scientists reported that the samples of comet dust that were returned to Earth embedded in aerogel contained the amino acid glycine, with an isotopic signature that indicates it was not formed on Earth. We'll talk with one of the scientists about the analysis and other work on the Stardust probe. |
