There's an isomorphism between life and stable structures. Most stable structures seem to be plentiful, and it isn't obvious whether it is because of nucleation/replication or because of independent emergence. There are plenty of galactic objects that beget other galactic objects in a self-propagating chain. Just look at what stars produce, and what stars form out of. Similar mechanisms apply to galaxy clusters. Are you familiar with prions? Well, their form of reproduction _is_ nucleation.
