POPSFrom a Distant Comet, a Clue to Life Within a few months, the Goddard scientists found glycine embedded in aluminum foil of the collecting apparatus. They had spent the time since then confirming that the glycine indeed came from the comet and not from contamination. “It’s not necessarily particularly surprising,” Dr. Elsila said of her extraterrestrial glycine in a phone conversation Tuesday. “I would have been surprised if it wasn’t there.” Dr. Elsila and her colleagues were able to show that the glycine from the comet had heavier quantities of the isotope carbon 13 than what occurs on Earth. They also detected a second amino acid, beta-alanine, but the quantities were too minuscule to confirm. The findings were presented Sunday at a Washington meeting of the American Chemical Society and will be published in the journal Meteoritics & Planetary Science.
