Citizens in southwestern China who were out and about on Wednesday evening were treated to a spectacular celestial light show thanks to a massive meteor that lit up the sky. Many in the region were celebrating the Mid-Autumn Festival and attempting to catch a glimpse of the full moon when the meteor stole the show.

周三晚,中国西南地区外出的市民们因一颗巨大流星点亮了天空而欣赏到了一场绚烂迷人的天空光秀。该地区的很多市民正在庆祝中秋节,在观赏月圆之时看见了那颗流星。

The space rock entered Earth’s atmosphere above China near the border of Myanmar bursting into flames with an estimated energy equivalent to 540 tons of TNT. It produced an extremely bright flash which lasted long enough for many witnesses to turn their smartphone cameras skyward and capture the rare sight.

这块太空陨石进入地球大气层后在中国与缅甸交界处爆发火焰,产生相当于约540吨TNT炸药爆炸时的能量。它发出了非常耀眼的光芒且持续时间长到许多目击者用手机将这一罕见景象拍了下来。

Many onlookers posted their own personal videos of the fireball on China’s Weibo social network (basically a Chinese Twitter). The videos show a small bright light eventually growing into a large flash before fizzling out temporarily providing enough light to mimic daytime.

许多围观者将他们拍摄的火流星视频上传至中国社交网络平台微博(相当于中国版的推特)。视频显示出该流星在消失前,从一个微小的明亮的光点最终变成一个巨大的光芒的全过程,其呈现的亮度将夜空照得如同白昼。

While it might look like the beginning of the apocalypse the impressive fireball hasn’t been lixed to any damage or casualties. That said local news reports have noted that it caused buildings to shake as it detonated in sky.

虽然它可能看起来像是末日的开始,但是那个瞩目的火流星并没有带来任何损坏和伤亡。当地的报纸也只是指出它在天空爆炸的时候引起建筑物摇晃。

According to NASA’s tracking of such fireballs — yes NASA documents every single one — the most recent fireball of similar size in China fell in 2014 so they’re not unheard of but they sure are neat to look at.  This most recent one is thought to have exploded over mountainous terrain which would make finding any resulting meteorites extremely difficult.

根据美国宇航局对此类流星的跟踪——对!美国宇航局记录着每一个呢!——最近一次在中国降落的相似大小的火流星是在2014年,所以他们并不是闻所未闻,但它们看起来的确很漂亮炫目。据认为,这次这个火流星是在山岭地区爆炸,这使得找到其产生的任何一块陨石碎片变得难上加难。

For a shooting star to make it on NASA’s fireball list it has to meet some minimum criteria. “A fireball is an unusually bright meteor that reaches a visual magnitude of -3 or brighter when seen at the observer’s zenith” the agency explains. “objects causing fireball events can exceed one meter in size. Fireballs that explode in the atmosphere are technically referred to as bolides although the terms fireballs and bolides are often used interchangeably.”

一颗流星要想列入美国宇航局的火流星名单上,它还必须满足一些最低标准。该机构解释说:“火流星是一种异常明亮的流星,在达到观测者顶点位置时可达到-3等亮度或者更亮。造成火流星现象的物体直径可达一米。在大气中爆炸的火球严格来说是指火流星,但火球和火流星的这两个术语常常互换使用。”
