What are examples of nebulae?
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
What is the names of the two most well-known nebulea?
Two well know nebulae are the Crab and Horsehead nebulae.
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'.
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.

When was Horsehead Corporation created?
Horsehead Corporation was created in 1848.
What are nebulaes made of?
Nebulae are made of clouds of hydrogen and other elements or clouds of dust (dark nebulae)
What is the symbol for Horsehead Holding Corp in NASDAQ?
The symbol for Horsehead Holding Corp. in NASDAQ is: ZINC.
What is the origin of the Horsehead Nebula?
The Horsehead Nebula can be found in the constellation Orion. Its name comes from its resemblance to a horse's head. The Horsehead Nebula was first discovered by Williamina Fleming in 1888.
In what year did Horsehead Holding Corp - ZINC - have its IPO?
Horsehead Holding Corp. (ZINC) had its IPO in 2007.
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 market cap for Horsehead Holding Corp ZINC?
As of July 2014, the market cap for Horsehead Holding Corp. (ZINC) is $1,002,019,838.56.
