Two Circular Green Nebula in Space

NASA Spitzer Space Telescope looked deep into the dusty nebula with an infrared radiation, and showed stellar infants who are lost in dark clouds, when viewed in visible light. More known as Messier 78, two circular green nebula cut from the surrounding dark cloud of dust. Dust, mostly dark, even for a telescope, but its edges appear in mid-wavelength infrared light, as luminous, red lights, surrounded by a bright rim. Messier 78 is easily seen through small telescopes in the constellation Orion, in the northeast  of  Orion’s Belt. Spitzer telescope has helped to penetrate this dust, revealing the glowing nebula from the inside. 

The light from young stars begins to cut a cavity in the dust and, ultimately, will help the nebula get the form of a large   glowing  green belt.  Stars that have not burned its way through the dust can be seen as red dots on the outside of the nebula.
