Astronomy Picture of the Day——印度上空的巨大喷流

Gigantic Jet Lightning over India

Explanation: Yes, but can your lightning bolt do this? While flying from Munich to Singapore earlier this month, an industrious passenger took images of a passing lightning storm and caught something unexpected: gigantic jet lightning. The jet was captured on a single 3.2-second exposure above Bhadrak, India. Although the gigantic jet appears connected to the airplane's wing, it likely started in a more distant thundercloud, and can be seen extending upwards towards Earth's ionosphere. The nature of gigantic jets and their possible association with other types of Transient Luminous Events (TLEs) such as blue jets and red sprites remains an active topic of research.

印度上空的巨大喷流

你曾经见到过这样的闪电吗？就在本月初，在从慕尼黑飞往新加坡的途中，一位旅客拍摄到了这场雷暴，并捕捉到一些意想不到的现象——巨大的喷流。这道喷流拍摄于印度巴德拉克的上空，照片曝光时长为3.2秒。尽管这道巨大的喷流看起来与飞机的机翼相连，但它很可能是从一片更遥远的雷云发出的，我们可以看到它朝着地球的电离层向上延伸。巨大喷流的本质及它与其他类型的瞬变发光事件（如蓝色喷流和红闪）的可能关联仍然是一个活跃的研究课题。
