When smaller stars such as red dwarfs or red giants use up all their fuel and nuclear fusion slows they start to die, and become small “white dwarf” stars which will emit white light until they finally darken into "black dwarfs".
Big stars like supergiants and hypergiants have shorter lives as they consume their fuel at a faster rate than smaller stars. As these massive stars die they explode as massive bright supernova.
Stars range in color depending on how hot they are, in order from lowest to highest temperature they are can be brown, red, orange, yellow, white, or blue in color.
The stars have played a very important role throughout human history. They have formed part of religious practices, been grouped into constellations, used in astrology star signs, helped to design calendars and were very important navigational tools for early explorations across land and seas
