Sh2 -132 is extensive emission nebula visible in the constellation of Cepheus .


It locates on the southern edge of the constellation, not far from the border with Lizard , along the plane of the Milky Way ; the best time for your observation in the evening sky falls between the months of July and December and is greatly facilitated by observers places in the regions of the ' northern hemisphere terrestrial.


Sh2-132 is located at a distance of almost 3200 parsecs (about 10400 light years ), putting it in the Perseus Arm , in the region of Cepheus OB1, a large, bright OB association . The stars responsible for the ionization of its gases are very hot and massive; in particular, we have identified two stars of Wolf-Rayet stars , known by the initials HD and HD 211 564 211 853 (the latter also having the initials WR 153), as well as a star of spectral class O8.5V and a dozen stars of class B. Around the star class O and one of the stars of Wolf-Rayet extends a bubble clearly visible in the band of radio waves , identified with the initials B Shell , probably originated from the stellar wind of the two massive stars. A structure similar but smaller, Shell A , hosts near its center a star class K. It is believed that in the nebula to have taken place in the past processes of star formation chain; currently these processes appear to be suspended, since there is no trace of recent activity. In the direction of the nebula are identified nine springs of infrared radiation [4] and a maser emission with H 2 O .
