408. What is the relationship between color and energy in stars?
Most stars that we see in the night sky appear silver or whitish to our eyes. In reality, the colours of the stars differ from one another, ranging from blue, yellow, orange and red. Different colored stars send out different kinds of energy. The blue stars send their energy through ultra-violet rays, while blue-white, white, yellow-white, yellow, orange and red stars send out their energy in heat waves.
