NASA Unveils Detailed Saturn Images from JWST, Hubble

NASA has unveiled the most detailed portrait of Saturn to date, combining observations from the James Webb Space Telescope and the Hubble Space Telescope to reveal intricate layers of the gas giant's atmosphere and rings. The images, released this week, blend infrared data from Webb with visible and ultraviolet light from Hubble, capturing the planet's dynamic features during its transition from northern summer toward the 2025 equinox.

The Hubble observations, taken in August 2024 as part of the decade-long Outer Planet Atmospheres Legacy program, provide crisp views of Saturn's banded clouds and subtle color variations, highlighting ammonia crystals, methane and other hydrocarbons that give the planet its characteristic yellow hues. Webb's infrared images, captured about 14 weeks later through Directors Discretionary Time, penetrate deeper into the atmosphere, sensing clouds and chemicals at multiple altitudes. Together, the telescopes offer a multiwavelength perspective that scientists describe as slicing through Saturn's atmosphere like peeling back the layers of an onion.

This combined approach uncovers a range of atmospheric phenomena. In Webb's view, a long-lived jet...
