Volcanoes on Io: Long-term Tracking with Adaptive Optics

Gemini North and W.M. Keck images of Io at different near-infrared wavelengths; the name of the filter is indicated in the black box at the start of each section. The bright spots are thermal emissions from Io’s myriad volcanoes. Note the increasing number of hot spots detected at longer wavelengths, i.e. towards the bottom of the figure.
