Orion Nebula False Colour

The Great Orion Nebula (M42) is a true showpiece in the night sky. It is easily visible to the naked eye as a fuzzy patch in the sword of Orion, and is a beautiful sight in telescopes of all sizes. It lies fairly close to our part of the galaxy, lying some 1500 light years distant. The center portion contains a tight grouping of stars called the Trapezium. M43 lies just above the Trapezium region, and another bright reflection nebula called The Running Man Nebula is near the top of this frame.
