"Jupiter's Moon Io: 4.5 Billion Years of Continuous Volcanic Activity"
TL;DR Summary
New images from the Juno orbiter reveal a lake of lava on Jupiter's moon Io, with an island within it, indicating signs of permanent volcanism. The volcanic activity has reshaped Io's surface, erasing impact craters, and the Juno team found smooth areas within the lava lake, possibly indicating the formation of obsidian glass. Additionally, research using the Atacama Large Millimeter Array (ALMA) suggests that volcanic emissions have been reshaping Io since its formation, providing insights into the moon's history of volcanism through the analysis of sulfur and chlorine isotopes in its atmosphere.
