NASA has released a new series of images showing Saturn in unprecedented detail, combining data from the James Webb Space Telescope and the Hubble Space Telescope.
The images, published on April 17, 2026, offer the most complete view of the gas giant to date by pairing Webb’s infrared observations with Hubble’s visible-light captures.
According to NASA, the collaboration between the two observatories allows scientists to examine Saturn’s atmosphere “like peeling the layers of an onion,” revealing its three-dimensional structure and enhancing understanding of its complex weather systems.
In the comparative image released by the agency, Webb’s infrared view—taken on November 29, 2024—shows horizontal bands with the poles appearing in a grayish-green hue, while equatorial regions shift from dark orange to cinnamon tones.
The rings stand out with a bright, neon-like glow due to their highly reflective water ice composition, and several of Saturn’s moons—Janus, Dione, and Enceladus—are visible as white points near the rings.
Hubble’s visible-light image highlights Saturn’s familiar yellow tones, which result from sunlight reflecting off ammonia crystals and hydrocarbons such as methane in the atmosphere.
The James Webb Space Telescope launched in December 2021, more than three decades after Hubble’s deployment in April 1990. Despite the gap in launch dates, their combined data provides complementary insights that allow researchers to study celestial objects with greater depth.
This imaging effort builds on the legacy of the Cassini mission, adding new layers of detail to scientists’ understanding of Saturn’s atmospheric dynamics.
The release underscores how multi-wavelength observations from different space telescopes can combine to produce a more complete picture of planetary bodies in our solar system.
