Westerhout 31 [SEP] constellation
Westerhout 31
Westerhout 31, also known as W31, is a complex of star formation regions of the Milky Way located in the constellation of Sagittarius.
Characteristics.
As happens with other similar star-forming regions, Westerhout 31's location in the Milky Way obscures it so much due to the interstellar dust located between it and the Solar System that it cannot be studied with optical telescopes and for its observation infrared telescopes such as Spitzer, radiotelescopes, or instruments able to detect X Rays and gamma rays are needed
Westerhout 40
Westerhout 40 or W40 (also designated Sharpless 64, Sh2-64, or RCW 174) is a star-forming region in our galaxy located in the constellation Serpens Cauda. In this region, interstellar gas forming a diffuse nebula surrounds a cluster of several hundred new-born stars. The distance to W40 is 436±9 pc (1420±30 light-years), making it one of the closest sites of formation of high-mass O- and B-type stars. The Ionizing radiation from the massive OB stars
