Why are the ionization nebulae so bright?
They are regions where gas is ionized by hot, young stars.
What are the two main types of bright nebulae?
emission nebulae and reflection nebulae.
Where are the ionization nebulae predominantly located?
within or on the edges of the spiral arms of the galaxy
Where are the ionization nebulae predominantly located in the galaxy M51?
within or on the edges of the spiral arms of the galaxy
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 is difference between dark nebulae and bright nebulae?
Bright nebula are clouds of gas and dust that shine by reflected starlight. Dark nebula are clouds of dust and colder gas that can be seen by their silhouette against brighter objects behind them in the line of sight.
Why doesn't the Horsehead Nebula glow like other nebulae?
Horsehead Nebula doesn't glow like other nebulae because it is older than other nebulae and was probably a lot smaller. In addition, Horsehead Nebula is farther away from the Earth than other nebulae, so it may seem that it doesn't glow as bright as other nebulae. No, this isn't right! The horsehead nebula doesn't glow for one reason - it isn't illuminated by any stars whose energy is enough to make the gas shine. That's the only difference between a 'bright' diffuse nebula (like M42) and a 'dark' one like the Horsehead or the Coalsack. M42 (the Orion nebula) is bright because there are several hot, energetic stars embedded inside it, and which cause it to 'shine'.
In which galaxy can you find an ionization nebula?
I could be wrong about this, but I don't think it's possible to observe nebulae (properly so called) in any galaxy other than our own, because they're too faint and too far away.
