JWST's unparalleled ability to peer into the shrouded hearts of distant clouds has revealed the elements of biochemistry in the coldest and darkest place we've seen them yet.
Although the elements and molecules detected in Chamaeleon I are quietly floating about right now, one day, they could be caught up in planet formation, delivering the ingredients necessary for the emergence of life to new baby planets.
Chamaeleon I is cold and dense, a dark conglomeration of dust and ice that constitutes one of the nearest active star-forming regions to Earth. A census of its composition, therefore, can tell us quite a bit about the ingredients that go into star and planet formation and contribute to an understanding of how these ingredients are incorporated into newly forming worlds.
JWST peered deeper into Chamaeleon I for a census of its composition than we've ever seen before. It found silicate dust grains, the aforementioned CHONS and other molecules, and ices colder than any measured before in space, at around -263 degrees Celsius .
