NASA's Hubble Space Telescope captured an image of a decagon-shaped cloud pattern around Saturn's south pole on September 8, 2026.[^2] The image was released as part of the Astronomy Picture of the Day service provided by ASD at NASA/GSFC, NASA Science Activation, and Michigan Tech. U.[^1]

The instrument was built by an international consortium spanning Europe and Chile, led by the UK Astronomy Technology Centre, part of the UK's Science and Technology Facilities Council.[^3] The read here is that a ten-sided polygon at a planet's pole is unusual, though the facts do not establish whether this shape is a transient feature or a persistent structure.
