Stars

                                                  Stars  
    If you went online and searched up "stars" the articles that pop up will be filled with words and sentences that a normal grade and/or middle school-er wouldn't understand. Now I'm going to try and change that. 
     On Earth, in the city, we can see very little stars in the sky. The reason behind this is that we have a ton of city lights that block our eyesight from seeing the bright stars. If we go into the country-side, we would see numerous amounts of stars since there is not a lot of light in the rural areas. 
    Stars can be born in several different types of nebulae. One type of nebulae is called an emission nebula. It's the most brightest and colorful nebula due to its different color gases and dust. 

Binary Stars

    Stars are made with the gases and dust in the nebulae. With a sudden jolt, the gases and dust begins to crash into each other making the center of the collision heat up. The hot center is called a protostar, and someday, it will become a star. Now , you may all think that the shining stars are just alone and individual. But that is not true. During the collision of the gases and dust, they sometimes divide into 2 - 4 stars. These groups are called binary stars. So when you look up in the sky and you see a star, think that maybe it's not just one, but multiples of stars grouped together. (Sometimes the separated parts, when forming the star, can actually become a planet, comet, or an asteroid.)
     Stars are made of mostly hydrogen and helium. In the core of our sun, scientists predicted that it has something known as plasma, this mixture of electrons and protons that were pulled apart by the hydrogen atoms. Astronomers think that the plasma is about 15 million degrees Celsius.
     According to astronomers, the stars brightness depends on  the surface temperature of the star. The hottest star is the blue star and the coolest is the red dwarf star. 
     As time passes, the stars become old and they become white dwarfs. White dwarfs are about the size of Earth. It, the white dwarf, keeps itself intact, unbroken, and from collapsing by high speed electrons moving all around it. Our sun will become one, billions of years from now.

Supernova

     The bigger the star, the faster it will die; However, the stars still live for a very long time. Stars die in a super huge explosion called supernova which is when the star's core collapses and explodes. 
    After the explosion, a neutron star or a black hole may appear. If the core of a supernova is about 1.4 to 3 solar masses, weight of the star, the protons and electrons continues and forms into neutrons. This process creates neutron stars. If the solar mass of the core is more than 3, then the core becomes a black hole.
     After the supernova, the gases and dust remains gets reused and the process of forming a star begins again.
