The Lion Nebula SH2-132

The Lion Nebula, also known as Sharpless 132 (Sh2-132), is a weak emission nebula near the constellations of Cepheus and Lacerta. It’s thought to be between 10,000 and 12,000 light years away. The main components of this emission nebula are hydrogen and oxygen gases, which are stimulated to a high energy state by ultra violet light from nearby stars and subsequently re-emit the light. The darker areas are “dark nebulae,” which are dust clouds that obscure light.

This image is a combination of narrowband wavelengths of light. A colour palette known as HOO (Ha, OIII). The reddish areas are Ha emissions and the blue is OIII.
