astronomy wonder : 太空炮弹 (astro bullet)

Just review my draft and find this interesting astronomy picture. Can you guess what has happend?

For those who can read chinese word, your answer can be found below or read the text i copied from the website.

For the english reader, i will summarize the picture.

Summary:

The bright white colour astro bullets are actually consisted of high pressure gas, which has a speed of 400 km/s, is 1000x the speed of sound.

Those astro bullets are made of iron atom. They are in "boilling state" now due to consistent collision between them. The orange trail left by them is their shockwave, which has length of 1/5 light year.

Those astro bullets can be found near Orion nebula. And Orion Constellation is more popular among us right_

Chinese:

科学家们介绍说，这些由高温气体流构成的巨大“炮弹”的速度高达每秒400公里，超过音速的1000倍，而“弹头”的直径则相当于冥王星公转轨道直径的10倍。

太空“炮弹”的弹头主要有铁原子组成，由于不断地发生摩擦，它们均已处于“沸腾”状态。从照片上看，这些“弹头”均呈明亮的蓝色。

当穿越由氢气构成的浓密云团时，上述巨大的“弹头”会激起一阵阵橙色“巨浪”－－其长度接近五分之一光年。

猎户座星云是一座年轻的大型天体构造，距离地球约1500光年。科学家们认为，在大约45亿年前，太阳便诞生在一座与其条件类似的星云之中。
