闪电只发生在地球上吗？否。我们太阳系的航天器已经探测到其他行星上的闪电，包括火星、木星和土星，金星、天王星和海王星上也可能有闪电。闪电是带电粒子从一个地方突然冲向另一个地方。在地球上，冰和水滴碰撞的气流通常会产生产生闪电的电荷分离，但在木星上会发生什么呢？来自美国宇航局木星轨道朱诺号宇宙飞船的图像和数据支持了之前的猜测，即木星上的闪电也是在含有水和冰的云层中产生的。在朱诺号拍摄的这张特写照片中，一个光学闪光在木星北极附近的一个大云涡中被捕捉到。在接下来的几个月里，朱诺号将对木星的夜间进行几次近距离扫描，可能会让这个机器人探测器捕捉到更多的数据和木星闪电的图像。

Does lightning occur only on Earth? No. Spacecraft in our Solar System have detected lightning on other planets, including Mars, Jupiter and Saturn, and lightning is likely on Venus, Uranus, and Neptune. Lightning is a sudden rush of electrically charged particles from one location to another. On Earth, drafts of colliding ice and water droplets usually create lightning-generating charge separation, but what happens on Jupiter? Images and data from NASA's Jupiter-orbiting Juno spacecraft bolster previous speculation that Jovian lightning is also created in clouds containing water and ice. In the featured Juno photograph, an optical flash was captured in a large cloud vortex near Jupiter's north pole. During the next few months, Juno will perform several close sweeps over Jupiter's night side, likely allowing the robotic probe to capture more data and images of Jovian lightning.
