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 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.

What two things are needed to create an emission nebulae?
hot stars and interstellar gas, particularly hydrogen
Emission nebulae like M42 occur only near stars that emit large amounts of?
ultraviolet radiation
What type of star is Nebulae?
Nebulae are not stars. They are places where stars are formed, so a single nebula would contain lots of stars.

Are all nebulae luminous?
Technically, no nebulae are luminous. The ones that appear as such have stars either within or near them, and the nebulae merely reflect the light emitted by these stars.

Thick clouds of gas and dust that surround stars are?
Nebulae (plural of Nebula) large clouds of gas and dust, created by the demise of other stars. These nebulae act as galactic "nurseries" for the creation of new stars and planets.

How many kinds of Nebula's are there?
*the correct term is nebulae. a nebulae is a could of many gases and dust, where stars are created. TYPES: Diffuse Nebulae- the most common type. it is interstellar, which means among the stars, and not part of any galaxy. Planetary Nebulae- completely unrelated to planets. planetary nebulae is when gas and plasma are formed after certain types of stars die. it sometimes looks like gas planets, like neptune and uranus, hence the name. Reflection Nebulae- clouds of dust that reflect the light of nearby stars, though they are not nebulae, because they do not create stars. Protoplanetary Nebulae- a point in the lifetime of an astronomical object (star). protoplanetary nebulae, or preplanetary nebulae, emit light, much like reflection nebulae Emission Nebulae- a could of ionized gas which emits colorful lights
How many stars form from nebulae?
it depends on how large the nebulae is. The largest of nebulae (in both distance and height) form the largest number of stars while the smallest of nebulae (in both distance and height) form the least number of stars. Therefore there is no fixed number for the number of stars that can be formed from a single nebulae (a variable amount of stars can be formed from one nebulae)
What type of star is Nebulae?
Nebulae are not stars. They are places where stars are formed, so a single nebula would contain lots of stars.
Why do astronomers study nebulae?
Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.
Where in space are stars born?
Nebulae
Where does a star form?
Stars form in a nebulae
