DescriptionIo Over the Years (PIA25964).jpg |
English: This composite image depicts the visible changes on the surface of Jupiter's moon Io in the region around Volund, as seen by three NASA spacecraft. The top left image of Io was taken by the JunoCam imager aboard NASA's Juno spacecraft on May 16, 2023. An annotated version of the same image at top right highlights the location of the Volund region where volcanic activity is known to take place. The bottom left image shows the Volund region as imaged by NASA's Galileo spacecraft in September 1996. The image is crisper than the one of the Volund region at bottom center – taken by NASA's New Horizons mission in February 2007 – because the Galileo's flyby distance was much closer. At bottom right is a zoomed-in view of the above JunoCam image with annotations highlighting the changes to the active volcanoes known as Volund A and Volund B. The growth of the darker gray diffuse areas in the vicinity of Volund A and B indicate two lava flows that have increased in size and surround the volcanoes. North is to the top of all images. https://photojournal.jpl.nasa.gov/catalog/PIA25964 |
