The two major advantages of having observing facilities outside our earth s atmosphere are : first , we can get sharper images of objects without the blurring effects of our atmosphere imagine seeing through a steamy room after you finish taking a bath . second , we can detect radiation from stars and galaxies in frequency bands that have been blocked by the atmosphere , such as ultraviolet , x - ray , and g - ray 在地球大氣外裝設(shè)觀測設(shè)施有兩大好處,首先,影像可更為清晰,否則大氣的阻隔會使影像變得模糊情形就像身處充滿蒸氣的浴室之中其次,我們可以偵察到那些從恒星和星系而來,卻被大氣層阻擋著的輻射,例如紫外線x射線和伽瑪射線。
