In January 2023, the Cheops satellite observed two special exoplanets, KELT-3b and TOI-560c for this educational challenge. During the hackathon our team of experts will guide you in discovering how to analyse the Cheops data to uncover the size, orbital period and distance, habitability, and composition of these two distant worlds. Follow along to uncover the properties of the exoplanets and become a real exoplanet detective.

Teams will have to complete a set of 5 activities tailored for students and freely available. This activity is presented in English, but the challenge materials are available in 21 languages. 

Students and teachers will have the opportunity to ask questions directly to the ESA Science experts: Kate Isaak, Maximillian Guenther, and Sandor Kruk, by using the Ask a Scientist feature.
