    You can also identify aminoacids in molecular clouds that go on to form stars and planets e.g. https://academic.oup.com/mnras/article/523/2/2876/7176071?login=false

    I’m just not sure if there is any research on whether this forms spontaneously on dust grains, like on a metal catalyst, or whether this is something ejected from a former star/planet that died…or…actual panspermia.

    Lots of organic molecules floating around in space eg https://www.aanda.org/articles/aa/full_html/2022/06/aa43575-22/aa43575-22.html
