Peering Beyond the Rainbow: Hubble Reveals Jupiter’s Secrets in New Light
Two views of Jupiter showcase the wealth of information provided by the spectral filters on the Hubble Space Telescope’s Wide Field Camera 3 (WFC3) science instrument. At left, the RGB composite is created using three filters at wavelengths similar to the colors seen by the human eye. At right, the wavelength bounds are widened beyond the visible range to extend just into the ultraviolet (UV) and infrared regimes. Humans cannot perceive these extended wavelengths, but some animals (such as mantis shrimp, whose eyes function similarly to certain sensors on some NASA missions) are able to detect infrared and ultraviolet light. The result is a vivid disk that shows UV-absorbing lofty hazes as orange (over the poles and in three large storms, including the Great Red Spot), and freshly-formed ice as white (compact storm plumes just north of the equator). Astronomers, including the OPAL team, use these filters (and others not shown here) to study differences in cloud thickness, altitude, and chemical makeup.

The iconic gas giant Jupiter has always captivated human imagination. Yet, peering beneath its swirling clouds and vibrant colors reveals a hidden world of complex atmospheric phenomena. Recent images captured by the Hubble Space Telescope, using its advanced Wide Field Camera 3 (WFC3) instrument, offer a glimpse into this hidden world, showcasing Jupiter’s secrets in a whole new light.
Seeing Beyond Human Vision
These captivating images utilize a range of spectral filters, allowing astronomers to analyze Jupiter’s atmosphere in unprecedented detail. While the left image presents a standard color composite, resembling what our eyes would perceive, the right image extends the spectrum beyond the visible range, including ultraviolet (UV) and infrared light.
While invisible to humans, these extended wavelengths reveal vital information about Jupiter’s composition and dynamics.
Unveiling Jupiter’s Atmospheric Secrets
Looking closer at the image revealed through these expanded wavelengths, we see fascinating details.
- UV-absorbing hazes: These remarkable areas, painted orange, reveal lofty cloud formations where UV light is strongly absorbed. These hazes are found predominantly over the poles and within prominent storms, including the legendary Great Red Spot.
- Freshly formed ice clouds: White patches signify the presence of freshly-formed ice clouds. These compact storm plumes, situated just north of Jupiter’s equator, showcase the planet’s dynamic and ever-changing weather patterns.
A Deeper Understanding of Jupiter
By analyzing the variations in color and intensity across these spectral images, astronomers can decipher crucial information about Jupiter’s atmosphere, including:
- Cloud thickness and altitude:
- Chemical makeup: Different gases absorb and reflect light at specific wavelengths, allowing scientists to identify and map the distribution of various chemicals within Jupiter’s atmosphere.
Exploring Jupiter through the eyes of Hubble empowers us to unravel the mysteries of this gas giant and gain a deeper understanding of planetary formation and evolution.
