The type of nebulae that are lit by nearby stars are called reflection nebulae.

Here's why:

* Reflection Nebulae: These nebulae don't emit their own light. Instead, they reflect the light from nearby stars. The dust and gas particles within the nebula scatter the starlight, making the nebula appear to glow. The color of the reflected light often depends on the color of the illuminating star.
