" When the solar wind blows out plasma it too causes a bubble : the heliosphere , " he explains .
他解释说：“当太阳风释放出等离子体时，它也会制造出一个泡泡：日光层。”
Understanding more about the heliosphere and its ability to filter out galactic cosmic rays could be critical for assessing the safety of human space travel , schwadron notes .
对日球层和它过滤宇宙射线的机制了解的越多，就越有助于评估人类星际航行安全性。
One possibility is that pressure from this external magnetic field has forced particles just inside the heliosphere to bunch together into a ribbon .
一个可能性就是外部磁场的压力强行把日球层内部的粒子压到了一起，形成了窄带。
Update ( 9 / 6 / 2012 ) : in an email , decker notes that the nature paper was based on data collected before february 2012 and that newer observations further complicate the question of when voyager 1 will leave the heliosphere and enter interstellar space .
The new findings may also help predict how the heliosphere varies in shape and size as it moves through the galaxy and encounters regions of space having different densities and magnetic field strengths .
