Sh2-132: Central Region of the Lion Nebual

Sh2-132 is a faint nebula in the border of Cepheus constellation approx. 11,400 light years away from our planet.

This is an emission nebula, where massive stars are responsible for ionizing the gas in this region. In particular, two Wolf-Rayet stars - WR152 & 153 (HD 211564 & 211853) are identified.

These stars are at least 20 times more massive than our Sun and they tend to be eruptive and possess extremely high solar winds.

One of the Wolf-Rayet star, are easily visible bubble in the radio wave band, and it is identified as Shell B, probably originating from the stellar wind of the two massive stars.
