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

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。

Solar storms bombard Earth with a stream of electrons and other charged particles that interact with gases in the atmosphere to generate colorful aurora.

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。

And in the charged atmosphere after this bail-out meddling politicians, as part-owners, would have a tempting lever over the banks.

Effects stemming from the Earth's atmosphere, from ocean tides and from the solar wind of charged particles were all found to be too small to explain the spacecrafts' extra velocity.

During the dinosaurs' time on Earth, "the atmosphere became charged with methane, which finally damaged the ozone layer and brought about great changes in the vegetation, " it added.
