The Orion Nebula (M42) is a starry nursery

  • The Orion Nebula is one of the most familiar celestial objects, easily visible to the unaided eye below the 3 stars of Orion’s Belt.
  • It's a place where new stars are forming and is a vast stellar nursery.
  • To locate the Orion Nebula, find the three medium-bright stars in a short, straight row that represent Orion’s Belt.
  • Next, find the curved line of stars “hanging” from the same 3 Belt stars, representing Orion’s Sword, and look for the Orion Nebula about midway down that Sword of Orion.
  • It's description is like a star encased in a globe of luminescent fog.
  • One can see the Orion Nebula with the unaided eye on a dark, moonless night, and it's visible nearly all year.
  • Modern astronomers consider it an enormous cloud of gas and dust about 30 light-years in diameter that's giving birth to approximately 1000 stars.
  • There's an Orion Nebula Star Cluster that's also thought to exist inside the nebula.
  • It seems to have a black hole at its center, reported by an international group of astronomers in 2012.
  • The Orion Nebula’s position is Right Ascension: 5h 35m; Declination: 5 degrees 23′ south.
