Sh2-106 , Sharpless 2-106 or S106 for short is a compact H-II area in the constellation Swan in the northern sky . The object is about 2000 light years away from the sun and has a diameter of max. 2 ly. A star that has just emerged with the designation S106 IR in the center, itself covered by dust, has caused the hourglass-shaped shape and the turbulence visible in it.
The bipolar nebula was discovered by Rudolph Minkowski in 1946 while searching the sky for planetary nebulae . Since S106 did not have the characteristic light spectrum, he listed it under peculiar objects . Stewart Sharpless discovered it independently in 1959 on photographic plates of the Palomar Observatory Sky Survey .
