Sh2-132, the Lion nebula

Constellation: Cepheus

The Lion nebula (Sh2-132) is a rich H-II region with star clusters, emission nebulae, and dark dust regions. Located in the southern region of the constellation Cepheus, the Lion nebula is roughly 10’000 Ly from Earth, in the Perseus Arm of our galaxy, the Milky Way. This is primarily an emission nebula with some massive stars responsible for ionizing the gas in this region. In particular, two Wolf-Rayet stars (WR 152 and 153) have been identified – with the designation HD 211564 and HD 211853. This whole region is believed to be an area of new star formation.
