是的，但你的樹能做到嗎？圖中呈現的是近處樹木的暗色枝幹與遠處極光的明亮輝光形成的視覺巧合。極光的瑰麗之美——加上它彷彿在模仿近在咫尺的樹木——令攝影師著迷到幾乎忘記按下快門的程度。從特定角度觀賞時，這棵樹的枝葉竟彷彿化作了極光。 所幸在極光形態徹底改變前，他回過神來捕捉了這令人驚歎的瞬間奇觀。極光通常由太陽爆發引發，當高能電子撞擊距地表約 150 公里的地球大氣層時便會形成。這場罕見的天地共舞發生於 2017 年 3 月的冰島。 天空驚喜：你生日當天（ 1995 年後）天體照片日（APOD）刊登了什麼圖片？
原文：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 captured 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. Sky Surprise: What picture did APOD feature on your birthday? (after 1995)
