Star : The amazing brightness of the universe

A star is a ball of gas so hot that it burns and glows. The temperatures of stars range from 2100°C to about 50,000°C. The color of a star is an indication of how hot It is. White stars are hotter than red ones, but some stars become even hotter and shine with a blue light.

The Big Bang : The birth of everything

The Universe Is everything that we can ever know - all of space and all of time. It is almost entirely empty, with small clusters of matter and energy. The Universe is about 15 billion years old, but estimates vary. The Big Bang explosion is how scientists think the Universe began 15 billion years ago.

The Earth : Something that you must know.

The story of the Earth began about 4.6 billion years ago when dust whirling around the newborn Sun started to clump into lumps of rock called planetesimals gravity, these planetesimals then clumped together to form the Earth and other planets
