Fav十万个为什么
为什么星空会闪烁？
1、大气折射：星光在穿过地球大气层时会发生折射，大气层的密度和温度不断变化，导致光线弯曲和强度变化，从而使星星看起来在闪烁。
2、大气湍流：大气中的湍流（小规模的风和温度变化）会干扰光线传播，使星光在不同方向上快速波动，造成闪烁现象。
3、星星本身的运动：恒星并非静止不动，它们在宇宙中移动，距离地球的远近和速度不同，也会影响光线的到达时间和强度，产生闪烁。
4、星光传播的介质：星光在穿过不同密度的星际介质时也会发生折射，类似于光线穿过不同密度的玻璃，导致星光出现闪烁。
5、观测者的位置和大气条件：观测者的地理位置、大气湿度、温度等条件也会影响星光闪烁的程度，例如在高海拔地区星光闪烁较轻微。
总之，星空闪烁是大气折射、湍流、星星运动、星际介质以及观测条件共同作用的结果，是宇宙和地球大气相互作用的一种自然现象。
