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.

Constellations

Groups of star form patterns in the night sky, which are called constellations. There are 88 well known constellations. The Sumerians, a Middle Eastern civilization, probably named them about 5,000 years ago. They called them after the shapes, objects or animals that they thought they looked like, or after mythological characters.
The largest is Hydra, the sea serpent, and the smallest is Crux Australis, the Southern Cross. Centaurus, the Centaur, has the most stars that can be seen with naked eye (a total of 94). Others include Aquila, the Eagle; Draco, the Dragon; Canis Major, the great Dog; and Orion, the Hunter.
