Why are emission nebulae associated with young stars?



Young stars have not moved far from the gaseous nebulae where they were born.



Only hot stars can ionize nearby gas; hot stars are high-mass, so must be young.



The dust that makes emission nebulae glow is destroyed by old stars.



Young stars produce the blue light that is scattered by emission nebulae.
