The James Webb Telescope unofficial feed has just released new raw images of Saturn, giving us a preview of what the world’s most powerful space telescope will soon reveal about the ringed planet.
The final production will clean up the noise and colorize the images, giving us a better look at Saturn than we have ever gotten before.
The images were taken using Webb’s Near Infrared Spectrograph (NIRSpec) instrument.
Many of the images released show Saturn completely white, like a blob of white on an inky black background. But the more interesting images show Saturn’s rings lit up bright while Saturn itself remains a dark gray against the blackness of space.

That likely has to do with the types of filters the telescope used, as Saturn and its rings emit infrared and near-infrared light at different wavelengths.
Another image (or actually, a composite of four images) shows Saturn’s rings likewise glowing bright, while Saturn’s cloud bands are also visible.

Planetary scientist Leigh Fletcher of the University of Leicester in the UK led the team who commissioned the work. Officials hope to use Webb’s NIRSpec instrument to learn more about Saturn’s rings and moons.
Already this year, new discoveries have challenged what we thought we knew about Saturn and its many satellites. In May, 62 previously unknown satellites were discovered around Saturn, including some as small as 1.5 miles in diameter. Saturn now has 145 officially recognized moons in its orbit.
