Scientists have proven: without knowing the temperature of the interior and rock composition, it's easy to confuse life with lifeless processes.

On Saturn's moon Enceladus, water fountains erupt from cracks. Their analysis could point to life, but non-living chemistry can create similar 'clues.' To avoid confusing a rock with a microbe, precise data on the interior temperature is needed — otherwise the signal of life will simply be missed.

🎯 Enceladus's geysers eject water so fast that it flies into space and feeds one of Saturn's rings.

🎬 In Arthur C. Clarke's novel '2010: Odyssey Two,' an intelligent force forbids humans from landing on Europa because there, under the ice, evolution is just beginning.
