Inspired by the Voyager missions, CBeebies Stargazing: Space Explorers takes pre-schoolers on a journey of discovery through the Solar System. Robert the Robot tells Chris, Maggie and the Stargazers that the final stop on their journey is the planet Neptune. Maggie explains Neptune is the last planet in our solar system, over four billion kilometres away from planet Earth.

In Mission Control, Robert receives a final update from Astronomer Edward, who uploads a picture of Neptune for Stargazers everywhere to look at. Just as Robert is about to enjoy a tasty cake, another message comes into Mission Control. This time it's from Chris, Maggie and the Stargazers, they’ve made it to Neptune!

Maggie then reveals that when Voyager made it to Neptune, it discovered that there were extreme winds on the planet. The Stargazers feel the power of the wind for themselves when they travel in boats across the lake. More Stargazers then send an update back to Mission Control to inform Robert that both Voyager 1 and 2 are still out there exploring space. They also reveal that the spacecrafts carry a golden record, which has messages, music and pictures from planet Earth. This gives Robert an idea and he surprises Chris and Maggie with messages from Stargazers everywhere about their favourite things on planet Earth.

Maggie has one final solar system surprise of her own however, and she shows Chris a picture Voyager took on the edge of the solar system. In the picture, planet Earth is a tiny blue dot. Maggie reminds Stargazers everywhere to look after their planet and each other. Show less
