The Rose is the larger nebula, the bottom half of the image. It is also known as the Great Orion Nebula. In the Messier Catalog it is M42. The orb near the center of the image is M43. The nebula at the top of the page is known as the Running Man. Resembling a person with outstretched arms and legs. These objects are really easy to find in the night sky. It's actually the Sword, or the sheeth of Orion. These are the three 'stars' located just below Orion's belt. These 'stars' aren't exactly just stars. When you see the sword of Orion you are actually looking at this. However only the brightest points of light are actually visible. The top 'star' in the sword is actually the open cluster of stars inside of the Running Man. While the center star is actually the core of the Great Orion Nebula (or Rose). The bottom star in the sword is actually a handful of bright stars just outside of the Orion Nebula. The Orion nebula is actually one of the few things in the night sky that is forgiving enough to see in virtually any telescope, in any conditions, under light pollution, moonlight, etc, and still see a good portion of it with you're own eyes. It's also theoretically bright enough to actually see some of the color as well, for that though you'll need a strong pair of eyes, a really big aperture telescope under some really good conditions.
The Trapezium at the core of M42
Near the center or 'core' of the Great Orion nebula is the 'Trapezium' This is 4 very hot and bright stars. These stars are responsible for illuminating much of the nebula around it.
The Orion nebula appears very large compared to other objects. It happens to be in our 'Galactic Neighborhood' If you think of the Milky Way as a large city, the center being in downtown, Then the Sun and our Solar system would be a house in an a suburb closer to the outer edge of the city. The Orion nebula would be a large factory down the street from us. It's a stellar nursery, many stars have been born here and continue to be born from these clouds of dust today. It is thought that the Sun would have been born from this star 'factory' since it's one of the nearest to us.
