Circumplanetary disks can produce complex organics — Europa and other Jovian moons may have been born with prebiotic material

New research shows complex organic molecules (COMs) can form in circumplanetary disks around gas giants, meaning moons such as Europa may have accreted intrinsic supplies of prebiotic material. That raises the likelihood of locally available organics independent of later meteoritic delivery.
