The JunoCam instrument aboard NASA's Juno spacecraft captured two volcanic plumes rising above the horizon of Jupiter's moon Io on Feb. 3, 2024. Mission scientists think the plumes were emitted either by two vents from one giant volcano, or two volcanoes near each other. The JunoCam instrument imaged the plumes from a distance of about 2,400 miles (3,800 kilometers). Citizen scientist Andrea Luck made this image from raw JunoCam data. https://photojournal.jpl.nasa.gov/catalog/PIA26340
