◆ Question 1st ----- What makes stars appear to be higher in the sky?

◆ Answer----- Due to atmospheric refraction , the stars seem to be higher in the sky than they actually are. Light from a star is refracted as it leaves space and enters in the earth's atmosphere.Air higher up sky is rarer but that near the earth's surface is denser.So as the light from a star comes down , the denser air bends the light more.Due to this refraction of star's light, the star appears to be at a higher position.
