The ALMA images were taken when Io passed into Jupiter's shadow in March 2018 (eclipse), and from Jupiter's shadow into sunlight in September 2018. These radio images for the first time show plumes of sulfur dioxide (in yellow) rise up from the volcanoes on Io. Credit ALMA (ESO/NAOJ/NRAO), I. de Pater et al.; NRAO/AUI NSF, S.
