Noisy JunoCam Image

July 18, 2025
The graininess and horizontal lines seen in this JunoCam image show evidence that the camera aboard NASAs Juno mission suffered radiation damage. The image was taken Nov. 22, 2023.

This image capturing one of the circumpolar cyclones on Jupiter's north pole was taken Nov. 22, 2023, by the JunoCam imager aboard NASA's Juno as the spacecraft flew past at an altitude of about 10,880 miles (17,500 kilometers). The horizontal lines and overall graininess of the image show the effects of radiation damage on the camera. The Juno team has been experimenting with a technique called annealing to address the damage and restore the quality of JunoCam images.
