Description

Also known as Orion Nebula, this is the brightest and one of the closest region of ionized hydrogen, star forming.

The cloud is lit up by by stars in a very young cluster, referenced as Orion Nebula Cluster, with about 3500 stars situaded in the heart of the nebula. Most of the stars in this cluster is obscured by the dense material present in the nebula.

Light from these stars are scatered off by dust, mainly in the outer region of the nebula and some are re-emitted by gas, particularly in the inner region, making M42 a emissing and reflection nebul

at the same time.

Four stars in the cluster form a quadrangle called The Trapezium which is in the most bright area of the nebula.
