The planet has a relatively thin atmosphere composed mostly of nitrogen and oxygen.

这颗行星有相对较薄的大气层，主要由氮气和氧气组成。

In the process, the particles collide with atoms of nitrogen and oxygen in the Earth's atmosphere, which then glow, creating an effect similar to miniature neon signs.

在这个过程中，太阳粒子会同地球大气中的氮原子和氧原子撞击并发出光芒，从而制造出类似于微型霓虹灯效果的极光。

Auroras occur when charged particles from the sun collide with Earth's upper atmosphere, causing atoms of oxygen and nitrogen to gain energy and then release it in the form of light.

太阳的带电粒子与地球上层的大气相撞，促使氧和氮原子获得能量，然后以极光的形式释放出来。

The atmosphere is about twenty-percent oxygen and eighty percent nitrogen from Earth's surface to where space begins at one-hundred-twenty kilometers up.

The scientific explanation - streams of charged particles from sun storms interacting with electrons in nitrogen and oxygen atoms in the earth's upper atmosphere - does little to demystify the experience.

This will produce a new atmosphere, which will consist not of oxygen and nitrogen but of vaporised rock.
