Io, a moon of Jupiter, is considered the most volcanic body in our solar system. A recent discovery by NASA using the Juno probe reveals a massive hotspot of volcanic activity in Io’s southern hemisphere, which produces enough energy to match six times the total output of all power plants on Earth. This finding is significant not only for its proximity to Jupiter but also because it sheds light on the moon’s unique geological features and potential insights into volcanism elsewhere in our solar system.
