Amateur astronomer's backyard sighting corroborates Saturn's new decagon wave

A ten-sided atmospheric wave circling Saturn's south pole, first flagged in Hubble data, gets independent confirmation from an Australian amateur observer.

What to know

  • A giant ten-sided 'decagon' wave has been identified encircling Saturn's south pole, the first large regular-sided jet pattern seen in that hemisphere.
  • The finding rests on years of Hubble Space Telescope observations and was independently corroborated by an amateur astronomer's ground-based sighting.
  • The decagon joins Saturn's already famous hexagonal jet stream at the north pole, adding a new data point on gas-giant atmospheric circulation.

    Further reporting details the wave's structure and jet streams

    Additional coverage describes the decagon as intertwined with strong jet streams spanning multiple atmospheric levels, offering insight into circulatory processes in gas-giant atmospheres.

  2. background

    Amateur astronomer's backyard sighting corroborates the decagon — A former Australian miner turned amateur astronomer independently spotted a ripple on Saturn from home, a sighting that helped confirm the decagon documented in years of Hubble data.

    NASA/ESA highlight the decagon as a first for Saturn's south

    An official NASA/ESA space-updates social account publicizes the find, calling it the first large, regular-sided jet pattern ever observed in Saturn's southern hemisphere.

    “Scientists discovered a giant 10-sided atmospheric wave—a decagon—encircling Saturn's south pole! Captured by Hubble Space Telescope, this is the first large, regular-sided jet pattern ever seen in the planet's southern hemisphere.”
