The Orion Nebula

The Orion Nebula has many different names including Messier Object 42, M42, NGC 1976, the Great Nebula, and Ensis

Estimated to be 30 light years across

One of the brightest nebulae and is visible with the naked eye

Closest area to earth in which stars are being formed

The Orion Nebula is part of the much larger Orion Molecular Cloud Complex

Scientists have witnessed protoplanetaray disks, brown dwarfs, turbulent motins in the gas, and the photo-ionizing effcts of nearby massive stars, all of which have given us much information on how stars and planetary systems form.

The Orion Nebula is home to the Trapezium Cluster. The Trapezium Cluster is a very young cluster of stars that were formed at the same time and are still lossely gravitationaly influenced by one another.

Nicolas-Claude Fabri de Peiresc is generally credited with having first discovered the nebula in 1610.

The Trapezium Cluster was first discovered by Galileo Galilei in 1617.



This is a emission nebula AKA "The Great Nebula In Orion." IT is seen as the middle star in the sword of orion by the naked eye easily. It is 1500 light years away from earth. At the heart of the nebula is four hot and bright system called "The trapezium," wich power the M42 by its light. the M42 is larger than the M43, making look like its one. The emission nebula is high temperature gas clouds. The atom are energized by ultraviolet light by stars close to it and emit radiation in lower energy state. nebula are mostly red because predominant emission line of hydrogen. emission nebula are sites of ongoing and formation of stars.Blue dust reflects the light of new stars.
