Preplanetary disk

NASA/European Space Agency's Hubble Space Telescope has captured part of the marvelous Serpentine Nebula, illuminated by the star HBC 672. This young star casts an impressive shadow -- known as the bat shadow -- on the nebula behind it. Photo: Space Telescope Science Institute

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

Artist's impression of a disk surrounding a young giant star. Astronomers have for the first time been able to clearly look at a disk of dust closely surrounding a young giant star. This discovery provides direct evidence that massive stars form in the same way as their smaller brothers and thus closes a heated debate. The artist's rendering shows what such a massive disk might look like. Photo: ESO/L. Calçada
