Jupiter’s moon Amalthea casts a shadow on the gas giant planet in this image captured by NASA’s Juno spacecraft. The elongated shape of the shadow is a result of both the location of the moon with relation to Jupiter in this image as well as the irregular shape of the moon itself.
The image was taken on 1 September 2017 at 2146 GMT, as Juno performed its eighth close flyby of Jupiter. At the time the image was taken, the spacecraft was 3,858 kilometers (2,397 miles) from the tops of the clouds of the planet at a latitude of 17.6 degrees.
Citizen scientists Gerald Eichstädt and Seán Doran processed this image using data from the JunoCam imager. The image has been rotated so that the top of the image is actually the equatorial regions while the bottom of the image is of the northern polar regions of the planet.
