n.月球背面

Sometimes our view of the farside is blocked because the object spins so slowly. 有時(shí)，看不到背離我們的一面，是由于天體旋轉(zhuǎn)得很慢，致使我們的視線受阻。

As no astronauts have ever landed on the farside, we know little about its composition and history. 由于從來沒有宇航員在月球背面著陸，我們對月球背面的結(jié)構(gòu)和歷史幾乎一無所知。

The favored location- Saha Crater-is near the moon's equator and only three degrees onto the lunar farside. 薩哈火山口是最佳地點(diǎn)--它靠近月球赤道并且只在月球另一面的三度位置上。

Our galaxy, the Milky Way, has interesting things hidden behind its farside too. 在我們銀河系的背面也隱藏著有趣的景象。

If a giantmagnetic storm is brewing on the farside, it will hit Earth with a flood of radiation as it finally rotates into view. 如果另一面正在形成一場巨大的磁暴，當(dāng)另一面最終轉(zhuǎn)到朝向地球時(shí)，磁暴就會(huì)攜帶大量的輻射襲擊地球。
