Saturn has been photographed like never before: two of NASA’s flagship observatories—Hubble and the James Webb Space Telescope—have returned images that peel back layers of the planet’s atmosphere and reveal its rings in startling new detail. The pair of perspectives, one in visible light and the other in infrared, combine to tell a richer story about the gas giant’s storms, winds, and seasonal changes.
These images are more than eye candy. By comparing what Hubble sees in reflected sunlight with Webb’s ability to detect heat and deeper cloud layers, scientists can trace weather patterns and atmospheric structure across scales that were previously out of reach.

Hubble captures subtle color and cloud-top detail in visible light, making it ideal for tracking banding patterns, transient storms, and the fine color differences across the planet’s face. Webb, operating in the infrared, penetrates lower into the atmosphere and exposes deeper cloud formations, thermal contrasts, and emissions that are invisible in optical wavelengths.
Key observational facts
- Hubble’s shot was taken in August 2024 as part of the long-term OPAL (Outer Planet Atmospheres Legacy) monitoring program.
- Webb observed Saturn a few months later using Director’s Discretionary Time, giving researchers a complementary infrared look.
- The two observations were separated by about 14 weeks, showing Saturn’s changing appearance as it moves toward the 2025 equinox.
New atmospheric features revealed: jet ribbons, lingering storm scars, and southern convective activity
In Webb’s infrared view a sinuous jet known as the “ribbon wave” winds across Saturn’s northern mid-latitudes, revealing the imprint of deeper atmospheric waves that barely show up in visible light. A compact bright spot near that ribbon marks the fading trace of the massive Great Springtime Storm that roiled the planet in 2011–2012. Multiple other compact storms pepper the southern hemisphere in Webb’s image, evidence of vigorous convection below the cloud tops.
- Ribbon wave: a long-lived jet stream whose shape is driven by subsurface waves.
- Storm remnant: a small but persistent feature tied to the 2011–2012 superstorm.
- Southern storms: scattered convective cells that show up clearly in infrared.
These patterns are sculpted by winds and wave interactions under the visible cloud deck, making Saturn an outstanding natural laboratory for studying extreme fluid dynamics and atmospheric physics.
The polar hexagon: a rare, decades-spanning weather phenomenon
Saturn’s famous north-polar hexagon, first photographed by Voyager in 1981, remains faintly visible in both Hubble and Webb frames. The geometric jet feature has persisted through many seasons, underscoring the stability of some large-scale atmospheric processes on gas giants.
Because the northern pole is tilting into winter, Earth-based and space-based views will grow progressively limited: the pole will spend roughly 15 years in reduced sunlight, so these images likely represent some of the last high-resolution looks at the hexagon until the pole returns to sunlight in the 2040s.
Infrared surprises: polar glows, ring brightness, and possible auroral signals
Webb’s infrared data shows the poles with a distinctive grey-green tone at wavelengths near 4.3 microns. Scientists suggest two leading explanations:
- a layer of high-altitude aerosols that scatters or emits differently at those wavelengths, and
- auroral-type emissions produced when charged particles interact with Saturn’s magnetic field.
The rings stand out exceptionally bright in Webb’s image because they are largely composed of highly reflective water ice, which shines at infrared wavelengths when illuminated. In Hubble’s visible-light frame the sunlit face of the rings is still bright but reveals more of the shadows that the rings cast on the planet’s disk.
Subtle ring structures captured by both telescopes
- Spokes and fine structure in the B ring appear differently between infrared and visible observations.
- The tenuous F ring looks razor-thin and well-defined in Webb’s view, while it appears only faintly lit in Hubble’s image.
- Shadows and sunlight geometry highlight differences in how the rings and planet reflect and emit light at different wavelengths.
Seasonal context and what the observations mean for future studies
These 2024 images were taken while Saturn moves from northern summer toward the 2025 equinox, a shift that gradually improves our view of the southern hemisphere. As Saturn’s tilt changes through the next decade, astronomers expect progressively clearer views of southern atmospheric activity, peaking through the 2030s.
Long-term monitoring programs like OPAL provide a decades-long record of banding changes, storm cycles, and seasonal shifts. Webb’s sensitivity to infrared wavelengths now layers additional, deeper-probing information onto that record, helping researchers measure vertical cloud structure, thermal contrasts, and particle layers that Hubble cannot see alone.
By combining datasets from both observatories, scientists can track the evolution of individual storms, study how jet streams like the ribbon wave form and persist, and better understand how Saturn’s internal dynamics interact with solar-driven seasonal forcing—work that will continue as the telescopes return to the planet in coming years.
