WHY STARS ARE TWINKLING and WHY CONT SUN: the scientific name for this is SCIENTILLATION. NOTE:stars are twinkle when we seen from earth but not twinkle we seen from moon /other planets which dont have atmospheric gas's(O2,H2O,CO2 etc) stars (except for the sun)appear as tiny four in the sky.whenever the light travel through the many layer of earths atmosphere,the light of stars is bent(refracted )many times and in random directions.("light is refracted when its fencitys of medium is changes i.e at junction of glass and air ) in earths atmosphere also there is medium is form with cold air(high density),hot air (low density).so light must bent among layers.this random refraction results the star winking out. Those stars are closer to horizon is twinkle more than stars at ahead. Due light travel less distance in air. OFCOURSE sun also refracted in air but didnt noticeable to eyes because sun appear big enough. |
