A close-up of part of the nebula shows that the ring consists of large numbers of small clumps. Clumps are small regions in the nebula that are much cooler and denser than the rest of the nebula and contain molecular gas. Some of the clumps are beginning to develop tails (see e.g. at the lower right), behaving as comets the size of planets. The team counts as many as 20,000 clumps and estimates that about half of all gas in the nebula is in these clumps. Credit: JWST/NIRcam.
