How do we explore galaxies? Why does a star go out? Where do space probes fly to? Thanks to spectacular illustrations and many flaps, children land with a rover on Mars, they look at our seething hot sun up close and search for Earth-like planets with a giant telescope. In a playful way, they learn about our solar system and what we can discover in the night sky, for example, sparkling constellations, meteor showers or comets.
