Amaze, amaze, amaze! @NASAWebb teamed up with @NASAHubble, observing Saturn in complementary wavelengths of light to give us a richer, more layered understanding of its atmosphere. These images were each captured in 2024, just 14 weeks apart from each other. In both images, we’re seeing the sunlit face of Saturn’s rings; in Webb’s infrared view (slide 1), the rings look extremely bright because they are made of highly reflective water ice. Webb’s image also highlights the long-lived jet stream known as the “ribbon wave” across the northern mid-latitudes. The small spot just below that represents a remnant from the “Great Springtime Storm” of 2011 and 2012 with several other storms dotting the Southern Hemisphere. Saturn’s poles also appear distinctly gray-green in this image. This color could come from a layer of high-altitude aerosols in Saturn’s atmosphere that scatters light differently at those latitudes. Another possible explanation is auroral activity, as charged molecules interacting with the planet’s magnetic field can produce glowing emissions near the poles. Both images sense sunlight reflected from Saturn’s banded clouds and hazes. Hubble’s visible light view (slide 2) reveals subtle color variations across the planet while Webb’s infrared view senses clouds and chemicals at many different depths in the atmosphere, from the deep clouds to the tenuous upper atmosphere.
