Would you like to see your own space artwork on the ESA site? Here's your chance! Every month we explore a different spacey theme from technology and eclipses to astronauts and moons. 

Get ready to explore the unknown! Our oceans on Earth are full of mysterious creatures—from glowing jellyfish to giant squids, and even beings no one has ever seen. But what about oceans on other planets and moons in our Solar System, or in faraway exoplanet systems? Could there be strange sea animals living beneath icy alien seas or swimming through colourful, bubbling waters in space?
We invite you to imagine and draw the amazing ocean life that could exist here on Earth—or out in the universe. Dive into creativity and show us the underwater worlds of your dreams!

This month's competition: Underwater Mysteries 

Entries must be submitted by 30 June 2025. 

Artwork could be a drawing, a painting, model or even something digital… use your imagination!

We will select the best entries which will go into the Space Gallery and will receive a special prize from the European Space Agency.
