Orion Nebula One of our Greatest Hits The Orion Nebula, or Messier.

Reflection nebulae may also be the site of star formation. 2MASS Atlas Image Gallery: H II Regions, Star Formation Regions, and Reflection Nebulae. It is one of the brightest emmision nebulae, and is visible to the naked eye in the night sky. A good example of this is the Orion nebula. The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orions Belt in the constellation of Orion. M42 is a great cloud of gas spanning more than 20,000 times the size of our own solar system and its light is. Reflection nebulae and emission nebulae are usually seen together and sometimes are called 'diffuse nebulae'. Description: Known as The Great Orion Nebula, let’s learn what makes it glow. Reflection nebulae are usually blue because the scattering works better for blue light than red (this is the same reason that the sky is blue and sunsets are red). However, is enough to make the dust visible because the light reflects off of the dust. NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth, in a region of our Milky Way galaxy where new stars are being formed actively. The light from the nearby stars is not hot enough to ionize the gas of the nebula to make an emission nebula. Like fog around a street lamp, a reflection nebula shines only because the light from an imbedded source illuminates its dust the nebula does not emit any visible light of its own.

In astronomy, a reflection nebula is a cloud of dust which reflects the light of a star or many stars. The nebula glows because it reflects light from Rigel. Buy The Orion Nebula with reflection nebula NGC 1977 by Roberto Colombari as a wall art print at Posterlounge: Many materials & sizes available. The Witch Head reflection nebula (IC2118), about 1000 light years from Earth, is caused by the bright star Rigel in the constellation Orion.
