Basically, atoms of hydrogen from the star's core are slammed together under high heat and pressure. The result is a helium atom. That process of fusion is what releases heat and light into the outer layers. This process is scientifically referred to as "stellar nucleosynthesis.”

The star balances the outward pressure of the heat and light created by the nuclear fusion taking place in the core, by having its own gravitational pull which pulls the gases inward. This is what stops the stars from blowing themselves up.
So next time you are sat star gazing or watching the Sun rise and set peacefully, you’ll know that out there, those stars are gazing back, fiercely flaming their gases across the galaxies to light up our days and warm our nights. They certainly are not just a pretty bright light!

Biography of Thomas Alva Edison
By Silvana Mandeville
While still in school, he got bad grades and because of that, he dropped out of school. His mother, who had been a school teacher, taught him reading, writing, and arithmetic at home. However, one biographer described him as a very curious child who learned most things by reading on his own. As a child, he became fascinated with technology and spent hours working on experiments at home.
He began his career by selling candy, newspapers, and vegetables. With his week's profits he bought electrical and chemical equipment.
Seeing the development of an increasingly advanced world, he realized the importance of incandescent lamps for human needs. He was also willing to spend US $ 40,000 to make an incandescent lamp experiment which would run over two years. In total there were about 6000 pieces of material spent, before he finally found the first electric incandescent lamp that could burn 40 hours on October 21, 1879. In 1880, he was appointed chief engineer of the Edison Lamp Works. In 1882, for the first time, he installed electric lights in the streets and houses one kilometer away in New York.
