Twinkle-Twinkle Little Star………..

Hello friends, am here to tell you something about stars, which rocks up when you see them at night at sky. Stars seem to twinkle because we see them through the layers of the Earth’s atmosphere. As light passes through these layers, it is distorted so that the amount we actually see changes constantly. The stars nearest the horizon appear to twinkle the most because the light is passing through a greater depth of atmosphere. Stars do not twinkle when viewed from space, which is why telescopes in space, such as the Hubble, give the best possible view of distant stars and galaxies.
