Avid volcanic moon enjoyer, makes space images look nice
@spacemarschall.net if going with an image from that paper, I would suggest our “true” color reconstructions. Very approximate true color, SHARK-VIS in February didn’t have a proper blue filter but a general purpose “visible” filter. Hopefully to be remedied in time for the next Jupiter oppo

Thanks to SHARK-VIS instrument on the Large Binocular Telescope, we are now able to monitor Io's surface changes from Arizona, producing global maps at 50-100 km resolution (hopefully) every year.

To monitor how this activity, we have had to rely on spacecraft encounters from missions like Juno to track how it changes with time, though earth-based and space-based telescopes have allowed us to monitor the thermal emission given off by Io's active volcanoes. Until now.

Io is the most active body in the solar system, with volcanic eruptions changing its face with new lava flows and volatile deposits. Just last year, an eruption west of Illyrikon Regio in Io's south polar region created a lava flow field the size of the US state of Maryland in less than 2 months!

In December 2019, I made a series of predictions for the 2020s. Lots of wide misses (Alphabet break up, a President Elizabeth Warren), but some good calls (Biden winning 2020 election, missed Queen Elizabeth’s death by a few months). Then there’s this quarter or half credit:

And Io's volcanism isn't limited to its surface so we also reported on volcanic plumes observed by JunoCam. Plumes were observed at seven locations in 2023 and 2024 (and an eighth was observed at Tonatiuh by JunoCam in 2018/19). This includes the double plume observed at Xihe during orbit 58:

Animated gif of Juno/JIRAM 3.5-micron observations of Io from December 27, 2024. This gif covers roughly 45 minutes of time as Juno passed Io at a distance of 74,444 km. The eruption at West Illyrikon was so intense that it saturated the detector and caused internal reflections within JIRAM's optics
