description Sh2-106 Overview
Sh2-106, also called Sharpless 2-106, is a compact bipolar emission nebula and star-forming region in the constellation Cygnus. Its two lobes of glowing gas are separated by a dark lane of dust, producing a pronounced hourglass appearance. The structure is shaped by energetic outflows and radiation from S106 IR, a massive young star embedded near the nebula's center, making the object useful for studying the early evolution of high-mass stars.
help Sh2-106 FAQ
What is Sh2-106, and where in the sky is it located?
Sh2-106, also called Sharpless 2-106, is a compact bipolar emission nebula and star-forming region in Cygnus. Its two glowing lobes give it a recognizable hourglass outline.
Why does Sh2-106 look like an hourglass instead of a round cloud?
A dark lane of dust cuts between the two lobes, making the center look pinched. The visible shape is therefore a bipolar structure with two opposing regions of glowing gas.
Is Sh2-106 a planetary nebula?
No, Sh2-106 is described as a star-forming emission nebula rather than the expelled shell of a dying star. Its defining structure is two glowing lobes divided by central dust.
What should an image of Sh2-106 show?
Look for two bright emission lobes on opposite sides of a dark dust lane. Its location in Cygnus and its compact bipolar shape distinguish Sh2-106 from a simple round nebula.
