Question
Why are comets green
Answer
When a comet gets warm enough, it creates an extended, gas-rich cloud known as a coma around its nucleus. If the coma contains carbon-nitrogen and carbon-carbon bonds, the Sun's ultraviolet light will excite the electrons inside it, causing them to emit a green glow when they drop down in energy.
