An important amino acid called glycine has been detected in a comet for the first time, supporting the theory that these cosmic bodies delivered the ingredients for life on Earth, researchers said Friday.
Glycine, an organic compound contained in proteins, was found in the cloud around Comet 67P/Churyumov-Gerasimenko by the European Space Agency’s probe, Rosetta, said the study in the journal Science Advances.
Previous data from Rosetta has shown that water on Comet 67P/C-G is significantly different from water on Earth, suggesting that comets did not play as big a role in delivering water as once thought.More.
Our favourite physicist Rob Sheldon thinks comets played a role, and that sounds reasonable.
The big problem is that researchers seem to be trying to figure out how life originated absolutely by chance, without any information input, which seems unlikely. Raises the question, how many frybrained theories must we endure before coping with the basic problem: Too much information, too little time?
