The Novas, a family of space explorers, make an interstellar discovery that will change the course of history when they chance across an alien spacecraft and its ethereal substance: Star Dust.

Bored with cataloguing rocks, Adelaide accepts a challenge to a space race against Sol. But when Sol gets in trouble, Adelaide and Jet perform a heroic rescue and rediscover what being a Nova is all about.

The Novas discover a tiny black hole that keeps bouncing around in space; Jet creates a superfood that looks like a pickle.

After crash-landing while on a supply run to a research planet, the Novas come face-to-face with natives and a deadly gravity storm that threaten not only their lives but some life-saving research.

The Novas travel to a suspected Star Dust Planet, but instead find themselves trapped underwater by a sentient seaweed plant; Aubrina sends Sol out undercover to learn what the Novas are up to.

When a large comet appears on a collision course with Luna Port, the Novas take a huge risk to divert it, only to realise it's no comet at all, but rather a frozen spaceship presumed lost for nearly 100 years.
