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!
