Amino acids in a meteorite – – Science news5th December 1970
[Researchers] Provide evidence for the presence of amino acids of possible extraterrestrial origin in a meteorite that fell near Murchison, Victoria, Australia on September 28, 1969. The basic building blocks of proteins can and were formed outside of Earth.
Scientists confirmed in 1971 that the Murchison meteorite contained amino acids, mainly glycine, and that these organic compounds likely came from space (SN: 03/20/71, p. 195). In the decades since then, amino acids and other chemical precursors of life have been discovered in other fallen space rocks. Recent discoveries include compounds known as nucleobases and sugars, which are key components of DNA and RNA. The amino acid glycine was even discovered in space in the atmosphere of comet 67P / Churyumov-Gerasimenko. Such insights support the idea that life could exist elsewhere in the universe.
