When you look up at the night sky, planets seem calm and fixed. But a new study shows that nearby planetary systems can be violent and chaotic.

Hubble identified the largest known protoplanetary disk, revealing a turbulent, chaotic environment with material extending above and below the disk, offering new insight into planet formation.

What seemed like new planets around Fomalhaut were actually expanding dust clouds from violent planetary collisions seen by Hubble.
