Detailing never previously seen, the image shows Jupiter’s dim rings, its two tiny moons Amalthea and Adrastea, auroras generated over the north and south poles, and Jupiter’s Great Red Spot.
The Near Infrared Camera on the James Webb Space Telescope captured these images. Jupiter’s infrared emissions are invisible to the naked eye. That’s why the photos James Webb took were processed from his original image data. For this procedure, red tones represented light at longer wavelengths while blue tones represented light at shorter wavelengths.
Jupiter’s fainter rings may be seen in this image if one looks closely. The Voyager 1 spacecraft made the first discovery of Jupiter’s rings in 1979. The rings are made up of tiny black particles and are considered to originate from debris ejected after collisions between interplanetary dust grains and Jupiter’s moons.
The Great Red Spot of Jupiter shines dazzling white at the planet’s lower right equator. Sunlight is reflected off of Jupiter’s thick cloud cover, giving the planet a dazzling white appearance. The cloud cover is less dense in the darker regions.
