Webb Peers Into Frozen Heart of Molecular Cloud – Unveils Dark Side of Pre-Stellar Ice Chemistry - SciTechDaily

The discovery of diverse ices in the darkest regions of a cold molecular cloud measured to date has been announced by an international team of astronomers using NASA’s James Webb Space Telescope.

This image by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam) features the central region of the Chamaeleon I dark molecular cloud, which resides 630 light years away.

The cold, wispy cloud material (blue, center) is illuminated in the infrared by the glow of the young, outflowing protostar Ced 110 IRS 4 (orange, upper left).

If you want to build a habitable planet, ices are a vital ingredient because they are the main source of several key elements — namely carbon, hydrogen, oxygen, nitrogen, and sulfur (referred to here as CHONS).

An international team of astronomers using NASA’s James Webb Space Telescope has obtained an in-depth inventory of the deepest, coldest ices measured to date in a molecular cloud.
