Description

The Orion Nebula (also known as Messier 42, M42, NGC 1976 or Sh2-281) is a diffuse nebula situated south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae with apparent magnitude 4.0. It is 1,350 ± 23 light-years away and is the closest region of massive star formation to Earth. The M 42 nebula is estimated to be 24 light-years across (so its apparent size from Earth is approximately 1 degree).

Messier 43 (M43), also known as De Mairan's Nebula and NGC 1982, is a star-forming nebula with a prominent H II region in the constellation of Orion. It was discovered by the French scientist Jean-Jacques Dortous de Mairan some time before 1731, then catalogued by Charles Messier in 1769. It is physically part of the Orion Nebula (Messier 42), separate from that main nebula by a dense lane of dust known as the northeast dark lane. It is part of the much larger Orion molecular cloud complex.

NGC 1977 (also Sh2-279) designates an H-II region and the young open star cluster located in this star forming region.

This is my first attempt on these objects.
