The Aurora Tree

Explanation: Yes, but can your tree do this? Pictured is a visual coincidence between the dark branches of a nearby tree and bright glow of a distant aurora. The beauty of the aurora — combined with how it seemed to mimic a tree right nearby — mesmerized the photographer to such a degree that he momentarily forgot to take pictures. When viewed at the right angle, it seemed that this tree had aurora for leaves. Fortunately, before the aurora morphed into a different overall shape, he came to his senses and capture the awe-inspiring momentary coincidence. Typically triggered by solar explosions, aurora are caused by high energy electrons impacting the Earth’s atmosphere around 150 kilometers up. The unusual Earth-sky collaboration was witnessed in March of 2017 in Iceland.

说明: 你家的树有这么亮丽吗？这张影像呈现视觉上，一颗邻近的树之黝黑树枝和远方明亮极光的叠合。美丽极光和它看似在模仿邻近的树形，合起来让摄影者看得如痴如醉，几乎忘了拍照的任务。因为如果角度刚好的话，这颗树看似以极光为叶片。幸好，在极光的整体 外观变成其他完全不同的形状之前，他惊醒过来并拍下这张令人赞叹的叠合影像。通常由太阳爆发事件所触发的极光，源自高能电子撞击150公里高空及上方的地球大气所致。这个不寻常的天与地通力合作事件，在2017年3月出现于冰岛上空。
