What are stars? Stars are humongous balls made of a scorching substance called plasma. Did you know that stars can live for billions of years? Today I’m going to tell you all about stars and why they are essential to life, the lifetime of a star, and the afterlife of a star.

Protostars are the life before a star is created. If it collects enough energy, it will become a star. The core is 50% of the mass itself, but it’s only 0.00001% of the star’s size. The center of the star is the part of the star that creates nuclear fusion because it is the hottest part of the sun. It’s nine times hotter than the surface of the sun!  Nuclear fusion is when negative and positive protons collide. It creates a lot of heat for millions of years. After the star runs out of fuel, they will become a red giant about five years after. It is because the Helium of the star will become Carbon in three years. Carbon would become Neon in a deadly decay of its surface, which transfers high radiation in the form of the remaining plasma radiation in about one year. Neon would become plasma in about eight months, which would be through this cycle between Carbon, Neon, and Plasma, but half the plasma would become liquid Iron. The plasma would become Iron in about four months.

The star is now considered a white dwarf. Dwarf stars are still quite hot, but they are significantly cooler than a star in the middle of its lifetime. In millions of years, they will become red dwarfs. Red dwarfs cool down very quickly. In another million years, they become brown dwarfs. They are even cooler than red dwarfs. They are still about 1000 degrees Fahrenheit. Two of the same type of dwarfs can collide and become one stage of their life backward, like when two brown dwarfs crash into each other. It becomes a red dwarf. After 5,000 years, it will become a black dwarf. Its remaining power can make a protostar.    

Stars are essential to life because they can produce energy, heat, and a magnetic field for us. The power they can create comes from helium and carbon. When positively charged neutrons or protons and negatively charged neutrons or protons, it makes a large wave of heat and energy, but most of the heat would not reach our planet. The Sun also provides a magnetic field, which makes the Earth rotate. Stars are essential to life and have an interesting life cycle and afterlife. We can use stars most efficiently if we can add solar panels. Or using a thermoelectric generator by getting close to the sun. They can help us learn about the galaxy.
