The Orion Nebula, also known as Messier 42 (or M42 for short), is the nearest star-forming region to Earth, located approximately 1350 light-years away and is about 2 million years old. M42 is part of a larger stellar network — the Orion Molecular Cloud Complex (also known as the Orion Complex), one of the most active star-forming regions visible in the sky.
