Figure A

This image revealing the north polar region of the Jovian moon Io was taken on October 15, 2023, by the JunoCam imager aboard NASA's Juno spacecraft. Since the high latitudes were not well covered in imagery gathered by NASA's Voyager and Galileo missions, three of the peaks captured here were observed for the first time. Those mountains are seen at the upper part of the image, near the terminator (the line dividing day and night).

Figure A is an annotated version of the image with red circles indicating the locations of the three peaks first imaged by JunoCam.

At the time the image was taken, the Juno spacecraft was about 7,270 miles (11,700 kilometers) above Io's surface.

Citizen scientist Ted Stryk made this image using raw data from the JunoCam instrument, processing the data to enhance details.
