In a billion years, it seems, intelligent life might be as different from humans as humans are from insects. But what would happen in another ten billion years?

But we can still understand how they work by finding snapshots of the process at different evolutionary stages and putting these snapshots together into a conceptual movie. For stars, astronomers saw dispersed clouds of matter (“star nurseries”) in galaxies. Elsewhere they saw those clouds condens...
