A nebula is a region of interstellar gas and dust. 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.
Other types of nebulae do reflect light. 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.
Emission nebula glow and reflection nebula reflect the light form other stars
Crab Nebula:Pulsar wind nebulaSupernova remnantRadius of 5.5 ly6,500 light years awayOrion Nebula:Diffuse nebulaStellar nurseryRadius of 12 ly1,244 light years awayEdit: M1, the Crab Nebula, is related to the death of a star. The Orion Nebula, M42, is relateted to the birth of stars.
Orion is a constellation made up in the minds of the ancients to represent "Orion" a hunter in mythology. The Orion Nebula is a diffuse nebula located south or Orion's belt. It is an area of extensive star formation. It is only called Orion Nebula as it is seen within the constellation of Orion. See related questions
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.
At the centre of the Crab Nebula is the neutron star - Crab pulsar.
The Crab Nebula is a nebula.
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
Emission nebula glow and reflection nebula reflect the light form other stars
it is plop of a difference
A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas
The helix nebula is more close than the ring nebula, as well as much brighter and larger than the ring but with low surface brightness.
"Nebula" is a astronomical term for a cloud of gas and dust. "Nebulae" is the plural of "Nebula" and refers to more than one such cloud.

There isn't 'an' Eagle Nebula. There is 'the' Eagle Nebula. This is just the familiar name for a large cloud surrounding the Open Cluster M16. Nebulae come in all conceivable shapes and sizes, so they are all different from each other!

Imagine the inside of an orange juice carton and the inside of a milk carton. It is exactly like that only to a bigger scale.
