Tencent science news astronomers in our galaxy a large group of gas Nebula found the formation of amino acids precursor molecules - methylnitrile and ethylamine Life on earth is made up of macromolecules: amino acids make up proteins, nucleotides make up DNA and RNA Where do these life molecules come from? It's still one of the biggest mysteries in science In fact, it is very difficult to find amino acid molecules directly in space To get around this problem, a team of scientists in the United States used the giant "green bank" radio telescope in West Virginia to find the precursor of two amino acids, methylnitrile and ethylamine, which are in the early steps of the chemical reaction to form amino acids In recent years, astronomers have found more and more complex "interstellar molecules", such as glycolaldehyde and ethyl formate, the former is the simplest sugar, the latter is the aroma molecules emitted by aged (micro blog) wine and various fruits Although these two molecules are not very appetizing recently, they are not the most important When trying to capture new interstellar molecules, astronomers usually point their telescopes at the center of the galaxy There is a 150 light-year-old Nebula called SGR B2, which is one of the largest gas clouds in the galaxy, 40 times denser than other gas clouds The discovery of these amino acid precursors in interstellar gas means that they can seed life on newly formed planets (breeze)
