Saturn's north pole has worn a six-sided hexagon for more than 40 years. Now Hubble Space Telescope images show a 10-sided decagon emerging at the planet's south pole — the first large polygonal jet pattern ever seen in that hemisphere.

Lead center managing Roman's development, integration, and testing

NASA's Nancy Grace Roman Space Telescope is fully built and targeting a September 2026 launch — eight months ahead of schedule. Its 300-megapixel infrared camera has a field of view 100 times wider than Hubble's and will photograph a billion galaxies and discover more than 100,000 new worlds in its first five years.

The detection using JWST's mid-infrared instrument hit 3-sigma confidence, meaning a 0.3% chance it's statistical noise. If real, it's the strongest evidence yet of biology beyond our solar system.
