Reflection Nebulae

Reflection nebulae are clouds of gas and dust in space that are illuminated by nearby stars, causing the nebula to reflect the starlight and appear luminous. They are different from emission nebulae, which emit their own light due to ionization by nearby stars or other energy sources.

Reflection nebulae are usually blue in color, as the dust particles in the nebula scatter blue light more efficiently than other colors. The size and shape of reflection nebulae can vary widely, depending on the amount and distribution of gas and dust in the region, as well as the intensity and color of the illuminating star.
