The observations indicate that Saturn is approaching its northern autumn equinox in 2025.
, this instrument can split infrared light into its constituent wavelengths, enabling scientists to detect the distinct signatures of the diverse range of chemicals present in a planet's atmosphere.
The observations indicate that Saturn is approaching its northern autumn equinox in 2025, suggesting that the northern pole is entering prolonged periods of polar winter.The main image showcases this north pole in blue due to strong thermal emission. The image also exhibits a large 1500km-wide storm called the North Polar Cyclone , first spotted by the Cassini probe. The different color hues depict temperature variations at various stratospheric levels.
The new measurements indicated that the distributions of stratospheric temperatures and gases during this summer phase of Saturn's seasonal cycle differed significantly from those detected by the probe during northern winter and spring.
