Become a cosmic explorer with Braulio Guerra Mendoza in this astronomical adventure. We discover far-off galaxies, brightly-coloured nebulae and clouds of stars that shine like jewels in the sky. Weather permitting, we will look at the sun, safely, using a phone screen and a telescope that everyone will be able to use. To finish, we will send the universe a symbolic message with our very own cosmic ray. An experience for looking at the sky, but also leaving something there.
