Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay Astronomers have always looked at the stars. They have always been curious about their life cycle, as they discovered more information about it. They discovered that stars are created in clouds of dust. Dust clouds are called nebulae. They are very fascinating for astronomers. Have you ever wondered how stars continue to shine throughout their lives? Well, everyone has if they've ever thought about the stars. They are powered by nuclear reactions that sustain the star throughout its life. These reactions take place through the core of the star. Have you ever wondered why bigger stars die faster? I know yes. Bigger stars die faster because they don't have enough fuel to burn longer. This fuel is not gasoline or fossil fuels. Everyone needs to know how big stars die, so I'll tell you. They end up making a big BOOM. The only things that might remain after this could be a neutron star also known as pulsars, or if they are very large they could collapse and turn into black holes. All astronomers wonder how little stars die, so I'll tell you. You. Small stars pass through an expression called a planetary nebula throughout their lives. The stars will eventually become white dwarfs. When they run out of fuel, they cool to become a brown dwarf. The Sun For anyone wondering what the sun is, let me tell you that the sun is a STAR. Everyone who has thought about the sun has wondered how long it burns, what it is made of, whether other stars are that size or larger, and how it produces energy. I have always wondered what causes the climate on Earth. To answer everyone wondering how long the sun burns, astronomers believe the sun has been burning for 4.5 billion years (WOW). What makes up the Sun is superheated hydrogen and helium. Wow, it must be super hot if it stays very close to the sun. What powers the Sun is nuclear fusion (it releases energy) and transfers it to its surface. For anyone wondering if the Sun is the same size as other stars. To answer this question, it is surprising that it is about the same size as other stars. The reason Earth has weather is because the sun does it for us. Colors and Their Relationship to a Star To all of you readers, I am here to tell you that if the star is very hot, it will be in the blue area of ​​the color spectrum. You would think it would be red, but let me tell you, it's not. In fact, the coolest stars are red. I know this because it surprised me too. The truth is that the hotter the star, the more ultraviolet its color will be. This means it will be more in the blue zone. Scientist who discovered the stars, for anyone wondering about the people who collected information and discovered the stars, the person who discovered the first galaxy was called Azophi in the westerns. He discovered the Andromeda galaxy. It was a group of stars outside the Milky Way. Nicolaus Copernicus showed some.
