The story of the sun birth
- About 9 billion years after the Big Bang the pregnant universe gave birth to a huge, beautiful, hot baby (the sun) which is about 4.6 billion years old.
- A yellow dwarf star, the Sun is located in the middle of our solar system. It emits light as a form of energy. That includes visible light, radio waves, ultraviolet light, and infrared energy (heat). Additionally, it emits a stream of particles known as "solar wind" that travels to Earth. The mechanism in the star that converts hydrogen into helium and produces enormous amounts of energy is the source of all of this energy.
- Like many other stars in our Milky Way galaxy, the Sun is a star. It has been around for just over 4.6 billion years and will probably last for another as long. The Sun is around 100 times wider than the Earth. Its mass, 1.9891x1030 kg, is 333,000 times greater than the mass of the Earth. Additionally, the Earth may 1.3 million times fit inside the Sun.
The delivery
- The Sun is thought to have originated from a massive cloud of dust and ice particles around 4.6 billion years ago.
- The material gathered into a ball at the center of that massive cloud due to gravity.
- The enormous pressure within began a fusion reaction once this reached a large enough size.
- That ball heated up and shone as a result of the energy that was unleashed.
- The planets formed from the remaining portion of this cloud as a result of the Sun's energy pushing the remaining portion of the cloud away from itself.
The future of the sun
- After about five billion years, our own sun will grow up to the red giant phase. Its outer layers will swallow Mercury and Venus as well as Earth as it expands. If or not our planet will be swallowed by the red giant sun or whether it will orbit too closely is still up for debate among scientists. In any case, Earth's current state of life will end.
