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.

Why do they call a nebula a nebula?
"Nebula" comes from the Latin word for "cloud." Nebulae are large clouds of dust, hydrogen, helium, and other gases in space. The term was originally used to describe any celestial object with a hazy appearance.
How are nebulae formed?
Nebulae are formed when clouds of gas and dust in space collapse under their own gravity. As the cloud collapses, it can trigger the formation of new stars. The gas and dust that remain are illuminated by the newly formed stars, creating the colorful and intricate structures that we see in nebulae.
Is a nebula a galaxy?
No, a nebula is not a galaxy. A nebula is a cloud of gas and dust in space, while a galaxy is a collection of stars, gas, dust, and dark matter held together by gravity. Galaxies can contain nebulae, among other structures.
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).
What nebulas are in Capricorn?
In the constellation Capricornus, notable nebulae include the planetary nebula NGC 6905, also known as the Blue Flash Nebula, and the faint emission nebula IC 1296. While Capricornus is not particularly rich in prominent nebulae compared to other constellations, these objects provide interesting targets for astronomical observation within the region.

What type of star is Nebulae?
Nebulae are not stars. They are clouds of dust, hydrogen, helium, and other ionized gases in space where stars are born. Some nebulae can be observed because of the light of nearby stars reflecting off their gas and dust.
