天空中是什么？一个极光。本月早些时候，我们的太阳发生了一次大规模的日冕物质抛射，将一团快速移动的电子、质子和离子抛向地球。这层云的一部分影响了地球的磁层，并在一个突然的间隙的支持下，导致在北半球高纬度地区可以看到壮观的极光。这是一张特别上镜的日冕照片，摄于瑞典森林上空，俯瞰Östersund市。对一些人来说，这种由大气中氧气重新组合而成的闪烁的绿光可能看起来像一条大鲸鱼，但请随意分享它在你看来的样子。过去几年异常安静的太阳现在已经过去了。随着我们的太阳现在接近11年太阳磁场周期中的太阳活动最大值，像这样戏剧性的极光肯定会继续下去。开放科学：浏览天体物理学源代码库中的2700多个代码

What's that in the sky? An aurora. A large coronal mass ejection occurred on our Sun earlier this month, throwing a cloud of fast-moving electrons, protons, and ions toward the Earth. Part of this cloud impacted our Earth's magnetosphere and, bolstered by a sudden gap, resulted in spectacular auroras being seen at some high northern latitudes. Featured here is a particularly photogenic auroral corona captured above a forest in Sweden from a scenic perch overlooking the city of Östersund. To some, this shimmering green glow of recombining atmospheric oxygen might appear like a large whale, but feel free to share what it looks like to you. The unusually quiet Sun of the past few years has now passed. As our Sun now approaches a solar maximum in its 11-year solar magnetic cycle, dramatic auroras like this are sure to continue.
