Nebula

Introduction
Nebulae name is rooted in Latin, it translates to Gas or Cloud. This would accurately describe a Nebula. A Nebula is in fact a Gas and Cloud in Space. So is a Star however, so what makes a Nebula different? Well to put it into more specific meaning, a Nebula is a gossamer cloud of gas and dust in interstellar space. It can have a range of some hundreds of light years. These Astronomical articles are not small by any means of the measure I do declare. On the conjury, Nebulae are beyond colossal in stature.  I would dare to say, thou would not want to drive in this fog, thou would not be able to see the road clearly for thy entire life, even at light speed. The clouds on Earth have nothing on these odysseys. A few Nebulae we know of are The Eagle Nebula, Crab Nebula, Ring Nebula, Orion Nebula, Helix Nebula, Dumbbell Nebula, Horsehead Nebula, Omega Nebula, Lagoon Nebula, Eskimo Nebula, Veil Nebula, North America Nebula, Coalsack Nebula, Saturn Nebula, Pelican Nebula, Owl Nebula, Boomerang Nebula, Egg Nebula, Lemon Slice Nebula, Medusa Nebula, Ghost Nebula, Iris Nebula, Crescent Nebula & Flame Nebula. There are an estimated 3000 Nebulae in The Universe.  
The Origin of Nebulae
Nebulae come from The Explosion of dying stars. These explosions come from Supernovae.
Aftermath
Nebulae after being created become a space for star creation. A Nebulae becomes Star Nurseries.
Conclusion
Nebulae come from the explosions of dying stars. Nebulae in turn become the birthplace of new stars. It's like a Hydra, thou cut off one head, two more grow in its place; except in a Nebula, more than two stars are born. This cycle is similar to life's cycle of life, death and rebirth. Except maybe the order is a little different. One lives, one gives new birth to another or others than one dies.
