Hubble observations detect ten-sided cloud feature near Saturn's south pole

Observations by the Hubble Space Telescope show a decagon cloud pattern at Saturn's south pole, according to NASA News.

The short version

  • Hubble Space Telescope data revealed a ten-sided decagon cloud structure encircling Saturn's south pole.[NASA News]
  • The southern feature differs from the six-sided hexagon at the north pole, which was first identified in 1987 Voyager data.[NASA News]
  • Scientists hypothesize the shape may stem from wave interactions between fast-moving and slower-moving atmospheric gases.[NASA News]
  • Researchers have not yet determined the long-term stability of the newly discovered southern decagon.[NASA News]

Key facts

  • Hubble Space Telescope observations identified a 10-sided decagon cloud structure around the south pole of Saturn.[NASA News]
  • Saturn's north pole possesses a six-sided hexagonal cloud pattern detected in 1987 from Voyager mission data.[NASA News]
  • The geometric boundaries may result from wave interactions between rapid gas flows away from the poles and slower gas closer to them.[NASA News]

What remains uncertain

  • It remains unconfirmed whether the southern decagon is long-lasting or a temporary atmospheric formation.[NASA News]
  • The wave-interaction explanation for the polar geometric boundaries remains an unproven hypothesis.[NASA News]
