171225期:极地上空的火流星

极地上空的火流星

一道极亮的光闪现极区,它会是什么呢?摄影师原先是想拍摄一系列的极光照片,然后再把它们制作成一个延时视频。但是从黑夜变为白昼之时,这位天文摄影师很快意识到他看到了一些更壮观的景象。飞过北斗七星前方的不仅仅是一颗双子座流星,而是一颗像火球一样的火流星。这颗流星突然变亮并闪烁了几秒钟之后才消失。幸运的是,原先要拍摄极光的相机能够记录下流星的整个轨迹。这张照片拍摄于在双子座流星雨达到顶峰后的一晚,这个摄影师的位置就在俄罗斯摩尔曼斯克附近的洛沃伊湖附近,就在北极圈以北的位置。

Fireball in the Arctic

Explanation: Something very bright suddenly lit up the arctic — what was it? The original idea was to take a series of aurora images that could be made into a time-lapse video. But when night suddenly turned into day, the astrophotographer quickly realized that he was seeing something even more spectacular. Moving through the sky — in front of the Big Dipper no less — was a Geminid meteor so bright it could be called a fireball. The meteor brightened and flashed for several seconds as it went. By a stroke of good fortune, the aurora camera was able to capture the whole track. Taken the night after the Geminids Meteor Shower peaked, the astrophotographer’s location was near Lovozero Lake in MurmanskRussia, just north of the Arctic Circle.
