Why do
stars appear to twinkle ?
Stars are extremely large gaseous bodies
found in the universe. They emit enormous amounts of light and other forms of
energy. This enormous amounts of energy comes from the nuclear fusion
reaction taking place in them. The nearest star to our earth is the sun. Billion of stars can be observed in the night sky. When
observed they appear to twinkle. The light
emitted by the stars has to pass through the atmosphere before it reaches us. While
passing through the various layers the light is bent. This makes the light to
flicker. Thus , for scientific observation scientists observe stars from the
top of a mountain. This is because as we go high the air becomes thin and it
cause the twinkling effects to reduce.
