Hubble's view of the globular cluster M2: It's full of (weird) stars ESA/Hubble & NASA, G. Piotto et al.

Globular clusters just keep coming up in my writing lately. In my defense, they’re really interesting objects. Dozens of light years across, they can contain hundreds of thousands of stars all held together by their mutual gravity, circling their center of gravity on orbits like bees around a hive. Many of them are incredibly old, among the first objects to form in the Universe, and some of them orbiting the Milky Way are as old as the galaxy itself.
