Orion Nebula in Oxygen, Hydrogen, and Sulfur

Explanation: Few astronomical sights excite the imagination like the nearby stellar nursery known as the Orion Nebula. The Nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud. Many of the filamentary structures visible in the above image are actually shock waves - fronts where fast moving material encounters slow moving gas. The Orion Nebula spans about 40 light years and is located about 1500 light years away in the same spiral arm of our Galaxy as the Sun. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion. The above image shows the nebula in three colors specifically emitted by hydrogen, oxygen, and sulfur gas. The whole Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years.

Here it is in another pic (Trapezium just left of center):


And here is another nice shot of the Trapezium in high resolution:

The heart of the Orion Nebula.

The Orion Nebula is visible without a telescope. It's the sword hanging off Orion's Belt. (No, there is no galaxy there.)

Locator chart. I take it you can find Orion.
