AI Summary

NASA’s Hubble Space Telescope has captured a giant, evolving ten‑sided atmospheric wave encircling Saturn’s south pole, marking the first regular‑sided jet pattern seen in the planet’s southern hemisphere. The decagon, which extends through multiple atmospheric layers, resembles the north‑pole hexagon but shows distinct differences, indicating a potentially new atmospheric phenomenon. Researchers assembled several years of Hubble data from the OPAL program, noting subtle early hints of the structure before it became clearly defined. The discovery involved scientists from ESA, STScI, the University of Valencia, NASA‑GSFC, and UC Berkeley, with image processing by Alyssa Pagan.
