极光是由地球大气上层的气体分子与来自太阳的高能带电粒子相互作用产生的。

Aurorae are caused by the interaction between energetic charged particles from the sun and gas molecules in the upper atmosphere of the Earth.

太阳不停的以"太阳风" ，这是一个高能带电粒子流，攻击与其相邻的行星。

The sun zaps its planetary neighbours with the “solar wind”, a stream of highly energetic charged particles.

太阳风暴中的粒子和地球大气中的气体分子相撞，粒子把自身的一部分能量转化并灌注到气体分子的电子中，使分子中的电子呈现出一种激发即高能的状态。

Particles in the solar wind collide with gas molecules high in Earth's atmosphere, transferring some of their energy and boosting the molecules' electrons into an 'excited' state.
