Why does the constellation Scorpius contain so many bright stars?

Why does the constellation Scorpius contain so many bright stars?|||The constellation Scorpius along with Sagittarius lies directly in front of the galactic center. This means it lies along an area on the sky where gas and dust should be present on a spiral galaxy - the Milky Way. This is the Sagittarius Arm. As we all know that star formation is mostly present along the arms of a spiral galaxy and so is this region of the sky. The arms contain the most rampant star formation which is contained within OB Groups and open clusters. In this direction of the sky lies the Scorpius-Centaurus-Lupus OB Group. It contains thousands of B stars and some occassional O-type stars. Well, comparatively B and O-type stars are the brightest stars so that answers why the constellation Scorpius has so many bright stars.





Clear skies!|||Maybe because it is seen in the direction of the center of our Galaxy. But also maybe not because the winter stars around Orion are brighter, and that is almost directly away from the center of the galaxy.|||They are likely from the same recent star-formation area.|||Why not?
