Orion Nebula
About this celestial object
The Orion Nebula rises early in the year—a luminous star-forming region low over the horizon.
M42 is a nearby, bright H II region in Orion’s Sword and visible to the naked eye as a misty patch—a laboratory of star formation in the winter Milky Way.
The very low altitude and 80% humidity mute the light; a stacked 520 seconds still pull nebular filigree and the bright core from the edge of twilight.
At 250 mm and f/5, structure is suggested while the central region naturally saturates—a pleasing contrast of shine and glow.

Welcome to the Orion Nebula. Below Orion’s belt lies a glowing stellar nursery. We will visit the bright main nebula, its smaller neighbour and a bluish region farther north. Notice the different ways in which gas and dust reveal the light of stars.
Orion Nebula M42
The bright centre contains the Trapezium Cluster. Its hot young stars provide energetic radiation that makes the surrounding gas glow. In our image, this central region blends into a bright core. The extended wings of nebulosity show that this stellar nursery reaches far beyond its conspicuous centre.
M 43
North of the bright centre lies the smaller nebula M43. A dark lane of dust separates it from the main nebula in visible light. Yet it belongs to the same large star-forming complex. Compare its compact shape with the broad structures of M42: a shared origin can produce very different appearances.
Running Man Nebula
Our final stop is the Running Man region around NGC 1977. Starlight scattered by dust plays an important role here, giving the region a bluish appearance. The dark spaces are as much part of the scene as the bright areas. They reveal dust hiding light rather than shining conspicuously itself.
