M42 - The Great Orion Nebula
M42 is a region of active star formation. At its center, we can distinguish the Trapezium cluster, composed of relatively young stars, with ages between 300,000 and 1 million years. They are part of the star formation process underway in the nebula.
Its size is about 24 light years, this is a small area of the entire Orion Cloud. It is located about 1,500 light years from our planet.
Charles Messier observed the nebula on March 4, 1769, and he also noted three of the stars in Trapezium.
Messier published the first edition of his catalog of deep sky objects in 1774 (completed in 1771).
As the Orion Nebula was the 42nd object in his list, it became identified as M42.
