Something neat happens when you sort stars by color and brightness.

In this visualization of the stars in the globular cluster Omega Centauri, we can clearly see several groups of stars emerge from this sort: normal, main sequence stars; red giants; blue, horizontal branch stars; and white dwarfs. These are all stages in the lifecycle of Sun-like stars.

The universe is wild.

This streak on a Hubble photo, originally thought to be an imaging glitch, is actually a 200,000 light year trail of new stars formed by the wake of a black hole that was ejected from the galaxy at the top right.

For reference, that streak is about twice the diameter of the Milky Way!
