heliosphere

基本解釋

“First and foremost, this is a big surprise because we thought we know a lot about this region, the edge of the heliosphere,” McComas says.
“首先，這太讓人喫驚了，因爲我們認爲對日球層的邊緣已經(jīng)了解的夠多的了，”麥科馬斯說道。
One possibility is that pressure from this external magnetic field has forced particles just inside the heliosphere to bunch together into a ribbon.
一個可能性就是外部磁場的壓力強行把日球層內(nèi)部的粒子壓到了一起，形成了窄帶。
The heliosphere shields the solar system from 90 percent of energetic cosmic rays — high-speed charged particles that would otherwise bombard the planets and harm life.
日球層就像一個盾牌，擋住了90%高能宇宙射線。宇宙射線由高速帶電粒子組成，會轟擊星球竝傷害生物。

Measurements from August 25th onwards show a steep drop in the detected volume of cosmic rays from the heliosphere, just as the extrasolar rays are picking up.
