Detection of methanol shows comets are forming in distant solar system

16 June 2016 Astronomy Now

Astronomers have found the organic molecule methyl alcohol, or methanol, in the protoplanetary disc of TW Hydrae, 175 light-years from Earth — the first such detection of this chemical compound in a young planet-forming disc. Since methanol forms on the icy coatings of dust grains, this discovery provides a window into the region where comets are likely forming.
