It’s been two months since NASA unveiled the first images captured by the exceptionally powerful James Webb Space Telescope, and a pair of new composites taken by the observer’s infrared NIRCam showcase Jupiter’s aurora and unique characteristics in similarly striking detail.
Against a dark backdrop filled with hazy dots that are likely distant galaxies, the wide view features two of the planet’s moons, Amalthea and Adrastea, and its rings. According to the European Space Agency, which released the images, the dusty halos shown are one million times fainter than the gaseous mass they encircle.
For the close-up, astronomers applied three filters to the NIRCam to capture the tiny details of the largest planet in our solar system. Zeroing in on the Jovian atmosphere, the image shows two polar auroras shining through red hues, with brilliant greens and yellows swirling around. “A third filter, mapped to blues, showcases light that is reflected from a deeper main cloud. The Great Red Spot, a famous storm so big it could swallow Earth, appears white in these views, as do other clouds because they are reflecting a lot of sunlight,” the agency says.
Because the human eye can’t see infrared light, scientist Judy Schmidt collaborated with astronomers to make the planet’s details visible. (via Peta Pixel)
