Perched atop a mountain in Arizona, the Large Binocular Telescope (LBT) has enabled scientists to capture groundbreaking images of Jupiter’s volcanic moon, Io. The telescope’s newly installed SHARK-VIS camera has provided remarkably detailed snapshots, revealing features as small as 80 kilometers wide. Until now, such resolution was only achievable through spacecraft missions. The images unveil intricate details on Io’s surface, including overlapping lava deposits from active volcanoes near the moon’s equator. One image, taken in early January, showcases a dark red ring of sulfur surrounding Pele, a volcano known for its massive eruptions. This ring is partially obscured by white debris, representing frozen sulfur dioxide, from a neighboring volcano named Pillan Patera. By April, NASA’s spacecraft captured images during its closest flyby of Io in decades, revealing a fresh layer of erupted material from Pele, indicating ongoing volcanic activity. Io’s volcanic eruptions are driven by gravitational interactions between Jupiter and its other moons, Europa and Ganymede. Studying these eruptions provides insights into the moon’s surface evolution over its 4.57 billion-year history. The new images from LBT’s SHARK-VIS camera represent a significant advancement in planetary imaging, allowing scientists to observe resurfacing events on Io from Earth with unprecedented clarity. Prior to the installation of this camera, such observations were only possible through spacecraft visits. The team’s findings, published in the journal Geophysical Research Letters, highlight the transformative capabilities of SHARK-VIS and pave the way for further exploration of Io’s dynamic volcanic landscape.
