A map-projected montage comparing an area on Io imaged by @NASAJuno on Dec 30, 2023 (left) and Feb 3, 2024 (right). In the Feb 2024 image, specular reflections are visible whereas no such reflections are visible in the Dec 30, 2023 image. The reason: Different viewing geometry. pic.twitter.com/cl0gZR8S9T
