Why do emission nebulae appear red when they surround blue stars?
The color of emission nebulae is a result of the predominate gas or gasses in that nebulae. Different gasses glow in different colors. Blue, as the color of the star, indicates how hot the star is.
What types of nebulae exist in the universe?
The types of nebulae that exist in the universe include bright, dark and emission nebulae. Different nebulae are often named for their shape. More information can be found on "Sea and Sky".
What are the names of different nebulae?

What are the two main types of bright nebulae?
emission nebulae and reflection nebulae.
What is a diffuse nebulae?
In astronomy, diffuse nebulae is the general term for illuminated nebulae. The three types of diffuse nebulae are reflection nebulae, emission nebulae and supernova remnants. They are diffuse as opposed to the non-diffuse dark nebulae, i.e. the particles have spread out.

What are examples of nebulae?
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
Are planetary nebulae sites for planet formation?
No, they are ionized gases thrown off stars near the end of their fusion cycles. They are expanding clouds of matter, quite different from the nebulae in which stars form.
When was Nebulae - band - created?
Nebulae - band - was created in 1992.
Where does matter for star nurseries comes from?
Planetary Nebulae
What is the difference between reflection nebulae and emission nebulae?
A nebula is a region of interstellar gas and dust. Emission nebulae are clouds of ionized gas that allow red, blue, and violet light through. Generally, these nebulae appear reddish. Reflection nebulae are clouds of dust that simply reflect light from nearby stars. The dust particles of reflection nebulae usually only scatter blue light, so the appearance is blue. Other types of nebulae don't reflect light. Dark nebulae such as the Horsehead Nebula are so dense that they block light from other sources, such as background emission nebulae, reflection nebulae, or other stars.
