Whose spacecraft first discovered active volcanoes on Io?
Quick Answer
NASA’s Voyager 1. In 1979 it found active volcanism on Jupiter’s moon Io.
The Full Story
Voyager 1 observed plumes rising from Io and identified active volcanic eruptions, the first ever seen beyond Earth. The discovery surprised scientists because Io was expected to be geologically quiet. Its volcanism is driven by intense tidal heating from Jupiter and orbital resonances with other moons. Io remains the most volcanically active body in the Solar System.
