Sh2 -132 has an extended emission nebula visible in the constellation of Cepheus . It is located on the southern edge of the constellation along the plane of the Milky Way at a distance of about 10400 light years. The stars responsible for the ionization of its gases are very hot and massive; in particular two of Wolf-Rayet stars known by the initials HD 211564 and HD 211853 (the latter also having the initials WR 153), as well as a star spectral class O8.5V and a dozen class stars B. Around the O-type star 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 (Wikipedia).
