Explanation about the Gases, Color and Size of Stars
Stars are living like people do; they are born, live a long mid-life, and eventually die. Stellars are different sizes and colors that become giant balls of hot gas and change as they age, but it doesn't take change until over billions of years later. Astronomers have a strong sense of how stars are on the inside and out. Stars colors change because of their temperature. The coolest stars are the color of red and reach 5000 degrees Fahrenheit. The hottest stars appear to be the color of bluish-white and are over 90,000 degrees Fahrenheit.
