A young, still-forming star that produces so-called complex carbon molecules like ethanol and acetaldehyde has been glimpsed by the James Webb Space Telescope (JWST). The compounds it is making could be the building blocks of future planets.
Such protostars consist of large volumes of gas, or gas and ice, that slowly coalesce into stars under the pull of gravity. Complex carbon molecules, which can act as building blocks for life, have been observed in some protostar gas clouds, but a…
