NGC 3199 in Carina (the Keel)

on Sunday, July 17, 2022
NGC 3199 is a bright emission and reflection nebula located 12,000 light years away in the southern constellation of Carina (the Keel). The nebula has an arc shaped form and covers a distance of 75 light years. Near the center of the ring is located a "short - lived" Wolf Rayet star HD 89358 or WR18. These type of stars are hot, luminous and are loosing mass in the form of stellar wind at a high rate. Apparently the bow shaped arc was formed out of the stellar wind ejected from WR18. These winds can create strong shockwaves when they collide with the comparatively cool interstellar medium, causing them to heat up anything in their vicinity.
