哈勃望远镜在土星南极发现神秘十边形天气图案
使用哈勃太空望远镜的天文学家在土星南极发现了一个巨大的十边形大气图案，宽约16.8万公里，这是首次在该行星南半球观测到大型多边形喷流。

据发表在《科学进展》期刊上的研究结果，使用哈勃太空望远镜的天文学家在土星南极发现了一个环绕土星南极的巨大十边形大气特征，其跨度约为16.8万公里，即每边约1.678万公里。这是首次在土星南半球观测到大型多边形喷流图案，与数十年来环绕该行星北极的著名六边形喷流形成鲜明对照。
研究人员表示，根据对2023年以来哈勃观测数据的回顾，这个十边形似乎是在过去几年中逐渐形成的。科学家认为，这些多边形大气图案是由不同纬度快速移动的喷流之间复杂的相互作用形成的，尽管决定确切边数的内在动力学机制仍是一个活跃的研究领域。这一发现进一步证实了土星大气层是太阳系中最具活力、几何形态最异常的大气层之一。
Key facts
- Hubble discovered a ten-sided atmospheric pattern circling Saturn's south pole, about 104,250 miles across
- It is the first large polygon-shaped jet stream observed in Saturn's southern hemisphere
- It is a counterpart to Saturn's well-known hexagonal jet stream at the north pole
- The pattern appears to have gradually emerged over the past several years, based on Hubble data since 2023
- Findings were published in the journal Science Advances
