The Orion Nebula is one of the most interesting objects in the sky. To the naked eye, it looks like a star in the sword of the constellation Orion, but with binoculars or a telescope, you can see that it is actually a large glowing cloud of material.

Nebulae are stardust. The gas in nebulae is used to make new stars. Dying stars create nebulae from their gas. While stars are made of very hot, dense gas, the gas in nebulae is cool and spread out.

Logarithmic scales are used when the actual light intensities cover such a large range that it would be difficult to represent them on a linear scale.

The Orion nebula has been mentioned as a good example of an H II region, and it is also one of the most studied ones out there.
The Orion Nebula is a perfect laboratory to study how stars are born because it is 1,500 light-years away, a relatively short distance within our 100,000 light-year wide galaxy.
M42, The Orion Nebula is perhaps the most photographed deep sky object in the heavens, a vast nebula of gas and dust exquisitely lit by surrounding stars.

The Hubble Space Telescope has directly observed protostars in the Orion Nebula and the Eagle Nebula (in the Serpens constellation). The protostars it has observed have been prematurely exposed.
William Herschel observed the Orion Nebula in 1774, and described it as "an unformed fiery mist, the chaotic material of future suns".
A second known class of multiple stars consists of the young trapezia, named after the famous multiple star known as the Trapezium in the heart of the Orion Nebula.[6] Such systems are not rare, and commonly appear closse to or within bright nebulae.
Next he showed me M27, the Dumbbell nebula, and a little later M42, the Orion nebula. Both were spectacular and also resembled long exposure photos with the exception of the missing colour.

The brightest stars in the Orion Nebula as seen from Earth are those found in a cluster near the middle of the nebula. This cluster is known as the Trapezium. They are young, hot stars, some of which are exciting the gas around them.
The birth of stars is intimately connected with the presence of dust grains and molecules, as in the Orion nebula region of earth's galaxy. Here, molecular hydrogen (H2) is compressed to high densities and temperatures, dissociating the molecules.
This image of sections of the Orion Nebula shows stellar formation under way. Located in the Milky Way about1,500 light-years from Earth, the nebula formed from collapsing gas clouds, yielding many new stars.
Margaret studied the Orion Nebula extensively. William and Margaret were the first people to realize that some nebulae, like the Orion Nebula, consisted of amorphous gases (and were not a congregation of stars, like the nebula Andromeda).
It is about four times larger than the Orion Nebula. A part of it is known as the Keyhole Nebula, named by English mathematician and astronomer John Herschel in the 19th century.
This is the location of the Orion Nebula, one of the most-photographed objects in the sky, a mass of gas from which a cluster of stars is being born.
What HST did find were disks of matter around stars seen in silhouette against the Orion Nebula (called 'proplyds', for 'proto-planetary disks' (right).

Can you tell us what the closest star to the Sun, Alpha Centauri, is made of, what its measurements are, and if it has any special assets?
The variable has born in The Great Orion Nebula (M42) and jumped from the nebula. The star is just passing through IC405 by chance, and brightening the nebula by giving energy and activating the hydrogen molecules.

Roughly 100 of the brightest non-stellar objects are listed in a well known catalogue by the 18th century French astronomer Charles Messier. These objects are often refereed to by astronomers by their M numbers. For example, the Orion Nebula is the ...
more you look, the more you will see, and the better you will get. As a result, an experienced observer might enjoy deep sky objects in an 80 mm refractor, while a beginner with a light bucket next door is still struggling to find the Orion Nebula.
HII regions have typical kinetic temperatures of 10,000 to 20,000 K, and densities ~10 atoms/cm3. The most famous HII region is the Orion Nebula (Messier 42); photograph shows Stromgren sphere of the Rosette Nebula.
are seldom much like Stromgren spheres, and more often have much of the line radiation coming from an ionization front which is being driven into a surrounding dense cloud. O'Dell in particular has made this case, most clearly for the Orion Nebula.
Using his improved telescope, he discovered a satellite of Saturn in March 1655 and distinguished the stellar components of the Orion nebula in 1656.
