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'.

What is the difference between a dark reflecting nebula and light relfecting nebula?
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.

How are nebulae formed?
Nebula are formed when a star explodes, releasing its gas into a gas cloud (the nebula). the nebula then will eventually condense due to gravity and form another star.
What are nebula referred to as the building blocks of the universe?
The matter which comprises nebulae coalesce to form stars and then, possibly, other bodies in the stellar system such as planets, comets etc.
What is the name for a huge cloud of dust and gas?
Clouds of dust and gas in space are called nebulae, singular nebula. Using "nebulas" as the plural isn't exactly wrong as such, but nebulae is more traditional and makes people think you know Latin.
What is the horsehead nebulae made of?
hydrogen and other gases

What is a close nebula to Orion's nebula?
A nebula is a cloud of dust and gas in space. Some of the clouds block out the light from the stars behind. These are called dark nebulae. One of the best-known is the Horsehead Nebula. Other dust clouds reflect the light from the stars and shine brightly. These are called bright nebulae. : Edit: The Great Orion Nebula is M42. M43 is a close nebula close to M42.

What is the difference in shape between the nebulae and an eagle nebula?
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!
What are the other names for the nebula Sagittarius?
Sagittarius is a constellation which contains several well-known nebulae. These include the Lagoon Nebula (Messier 8), the Omega Nebula (Messier 17) which is also known as the Horseshoe Nebula or Swan Nebula, and the Trifid Nebula (Messier 20).

Nebula are formed when a star explodes, releasing its gas into a gas cloud (the nebula). the nebula then will eventually condense due to gravity and form another star.
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.
What are nebula referred to as the building blocks of the universe?
The matter which comprises nebulae coalesce to form stars and then, possibly, other bodies in the stellar system such as planets, comets etc.
Can Nebula exist only within your galaxy?
No, nebulae are not unique to the Milky Way, there are hundreds that have been identified outside it, and are generally assumed to be present in most if not all other galaxies.
