Unlike other radio broadcasts , short-wave transmissions , bouncing off the ionosphere , can connect any two points on earth .
和其他的无线广播不一样，短波传送能从电离层反射回来，连接地球上任何两点。
The ionosphere is distinguished from other layers of earth 's atmosphere because it is electrically charged through exposure to solar radiation .
电离层与地球大气的其他圈层是不一样的，因为它是暴露在太阳的辐射之下，故而带电。
This energy soon showered earth 's upper atmosphere , tearing apart atoms in a region called the ionosphere to a greater depth than an ordinary solar flare and causing them to glow .
Though full details have yet to be released , the bbc understands that scientists also observed a " huge " signal in the ionosphere before the magnitude 7.8 earthquake in china on 12 may .
This extra energy would be funnelled down towards the magnetic poles , so molecules in the ionosphere above these regions could be accelerated enough to escape ( see diagram ) .
