Near-infrared views of Io, recorded with adaptive optics at the Gemini North telescope, track the evolution of a very powerful volcanic eruption that began August 29, 2013. Due to Io's rapid rotation, each night shows a different area of the surface. The outburst waned in brightness on August 30th and September 1st, 3rd, and 10th.Katherine de Kleer / UC Berkeley / Gemini Observatory / AURA
