Glycine, a basic compound from which proteins are built of, has been found in the Wild 2 comet dust samples.
The abundance of this amino acid in comet dust may be a signal that life is common, and often seeded by comets and meteors: “The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare,” says Carl Pilcher, NASA astrobiologist working on the project.
