An artist's illustration of the protoplanetary disk surrounding the young star MWC 480. The ALMA telescope discovered the organic molecule methyl cyanide in the outer regions of the disk, where comets are thought to form. This is another evidence that organic chemistry is complex of the kind needed for life, it is universal. Figure: (NRAO/AUI/NSF)

Complex organic molecules, the basis of life, were discovered in the disk of a nascent solar system
