NASA releases stunning new Saturn images—and the gas giant has never looked so good
New images captured by the Hubble and James Webb space telescopes show Saturn in both visible and infrared light

A new cache of images reveal the planet Saturn in spectacular detail, capturing the gas giant in both visible and infrared light. The images, which were taken by NASA’s James Webb Space Telescope (JWST) and Hubble Space Telescope, show the planet’s turbulent atmosphere, offering the “most comprehensive view of Saturn to date,” NASA wrote in a blog post.
Hubble captured the planet’s reflected visible light and highlighted Saturn’s iconic yellow hues—which are, in part, a product of the sunlight-reflecting ammonia crystals and hydrocarbons such as methane in its atmosphere. JWST, meanwhile, looked at the planet’s infrared light to peer deeper into the layers of its atmosphere. The two telescopes were launched to space more than 31 years apart—Hubble in April 1990 and JWST in December 2021. But in concert, they offer complimentary data and imagery that can highlight features of the universe in new detail.

“Together, scientists can effectively ‘slice’ through Saturn’s atmosphere at multiple altitudes, like peeling back the layers of an onion,” NASA said in its blog post, which accompanied the images. “Each telescope tells a different part of Saturn’s story, and the observations together help researchers understand how Saturn’s atmosphere works as a connected three-dimensional system.”

The images reveal the turbulence within Saturn’s atmosphere, including jet streams, the remnants of storms and, in JWST’s images, a mysterious greenish hue around its poles—possibly a product of atmospheric gasses or evidence of “auroral activity” similar to the aurora borealis and aurora australis we see on Earth. Saturn’s rings of dust and rocky ice, lit up by the sun, are especially striking.
Hubble has observed Saturn for years, but the new observations and combined power of the venerable telescope and JWST will help astronomers better understand how the planet’s mysterious atmosphere evolves over time.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can’t-miss newsletters, must-watch videos, challenging games, and the science world’s best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
