- 这个能量很快显示到地球的外大气层,将在电离层中的原子击开,使它们发出比普通太阳耀斑使它们发的更亮的光。
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. - 在接下来的几个月里,MRO的轨道将重复经过火星的外大气层,这就是减速过程,它将轨道高度降低到只有280公里。
In the coming months, MRO's orbit will be circularized through repeated passages into Mars' outer atmosphere, a process known as aerobraking, shrinking its orbit to an altitude of only 280 kilometers. - 为了寻找答案,轨道上空的斯皮策太空望远镜对两颗太阳系外行星的大气层进行了仔细地观测,这两颗行星围绕着的恒星与太阳不同。
In an attempt to find out, the orbiting Spitzer Space Telescope made detailed observations of the atmospheres of two planets that orbit stars other than our Sun.
