About image
Sh2-106 is an emission nebula visible in the constellation Cygnus.
Its most evident characteristic is its markedly bipolar shape: indeed, when it was discovered in 1946 it was believed to be a planetary nebula.
The center of the nebula hosts a very young star of great mass surrounded by a disk of dust; the radiation from this star ionizes the gas in its vicinity, while the more remote regions simply reflect its light.
The lobes are composed of expanding material and are separated by a band of unilluminated clouds.
All this area is home to star formation phenomena.
The most widely accepted estimate for the distance of this nebula is about 1950 light years.
