Stars are like big, shiny balls of fire in the sky! 🌟 They are made mostly of gas, like the air we breathe, but much, much hotter. The main gas is called hydrogen, which is very light and floats around. When stars get super hot, they glow bright like the Sun!
At night, stars twinkle because their light travels very far to reach us. ✨
Stars are giant balls of super-hot gas, mostly hydrogen and helium. 🌟 These gases are so hot that they create light and heat, just like the Sun (which is actually a star too!).
Inside a star, hydrogen atoms squeeze together to make helium—this is called nuclear fusion. It’s like a giant power factory that makes the star shine!
Stars twinkle because their light passes through Earth’s moving air. 🔭
Stars are massive spheres of plasma (a super-hot, charged gas) composed mostly of hydrogen (~70%) and helium (~28%), with tiny amounts of heavier elements. 🌟
Their energy comes from nuclear fusion in their cores, where hydrogen atoms fuse into helium, releasing enormous amounts of light and heat. This process can take billions of years!
Stars vary in size, temperature, and color. For example:
Our Sun is a yellow dwarf (G-type) star. 🔆
