This Nebula is one of the brightest starforming and deepsky objects that is seen from Earth. Many wonder why this beautiful Nebula was not discovered before the invention of the telescope. This Nebula was discovered in 1610 by a French lawyer who reported seeing a cloudy nebulosity. Orion spans about 40 light years across the region and was seen by infared data collected from the Spitzer Space Telescope. The brightest portion of the nebula is centered at Orion's massive hot stars, known as the Trapezium Cluster. Recently, crystals have been found in the dark dusty filament within its prostellar envelope.
