Juno: Three views of Jupiter’s moon Io from three different instruments, taken December 21
Juno: Three views of Jupiter’s moon Io from three different instruments, taken December 21st 2018. Top photo is a JunoCam image, with a volcanic plume visible along the terminator. Second is a Stellar Reference Unit image taken after Io passed into Jupiter’s shadow, & was illuminated only by light reflected off Europa. Third one is a JIRAM infrared image, so the bright spots show heat sources, presumably volcanic features. The article mentions Juno also taking images with the Ultraviolet Imaging Spectrograph, but they neglected to include any with the press release. I’m not sure I’ve ever actually seen any images from it, come to think of it. Anyway, this is all coming from a probe that wasn’t designed to study Jovian moons, and doesn’t fly anywhere near them. -- source link
