SH2-132 (the Leo Nebula) is a large HII region known for its bright emission nebulae, star clusters, and dark dust patches. It is located in the southern constellation Cepheus, about 10,000 light-years from Earth, in the Perseus arm of the Milky Way galaxy.
Nebula Characteristics
SH2-132 is an emission nebula, where emission comes from the ionization of gas caused by massive stars within it. Among them are two Wolf-Rayet stars: HD 211564 and HD 211853.
Wolf-Rayet stars are among the most massive and hottest objects in the Universe. They have the following characteristics:
- Mass: exceeds the minimum of 20 times the Sun.
- Brightness: can be hundreds of thousands or millions of times brighter than the Sun.
- Color: white-blue, indicating extremely high temperatures.
- Activity: strong stellar winds and regular outbursts of matter.
These stars play a key role in ionizing the surrounding gas, giving the nebula its characteristic glowing appearance.
Star Formation Region
SH2-132 is considered a region of active star formation, where new stars are forming. Intense ultraviolet radiation from massive stars, as well as their stellar winds, create conditions for the compression of gas clouds, triggering the process of star formation.
Interest for observations
SH2-132 is an impressive object for astrophotography and scientific research. Its bright emission regions and Wolf-Rayet stars make it a popular target among amateur and professional astronomers.
Studying the Leo Nebula provides insight into star formation, the evolution of massive stars, and the interaction of stellar winds with the surrounding interstellar medium.
