    "headline": "Astronomers Discover Decagon on Saturn's South Pole, Joining Known Hexagon",
    "dek": "Astronomers discovered a 10-sided cloud pattern, a decagon, near Saturn's south pole using Hubble Space Telescope data.",
    "prose": "A team of astronomers discovered a 10-sided polygonal atmospheric structure, called a decagon, near Saturn's south pole, and the discovery was published in the journal Science Advances. [^1]\n\nNASA's Hubble Space Telescope captured a giant, 10-sided atmospheric wave encircling the south pole of Saturn, described as a decagon. [^2]\n\nA single side of the decagon exceeds 10,000 miles (16,700 kilometres) in length. [^3]\n\nEach side of the decagon measures approximately 16,800 kilometers, which is longer than Earth's diameter. [^4]\n\nScientists traced subtle signs of the pattern back to 2023, noting it has become increasingly distinct since then. [^5]\n\nThe decagon is a cloud pattern, not a solid structure, because Saturn has no defined solid surface; descending through its atmosphere would never reach a ground. [^6]\n\nThe decagon joins Saturn's known hexagonal cloud pattern at the north pole, which was first observed 44 years ago. [^7]\n\nThe discovery is the first time a large, regular-sided jet pattern has been observed in Saturn's southern hemisphere. [^8]",
