List of diffuse nebulae

This is a list of diffuse nebulae. Most nebulae are diffuse, meaning they do not have well-defined boundaries. Types of diffuse nebulae include emission nebulae and reflection nebulae

Close up on the Orion Arm, with major stellar associations (yellow), nebulae (red) and dark nebulae (grey) around the Local Bubble.
