Description
NGC 3324 is an open cluster in the southern constellation Carina. It is associated with the emission nebula IC 2599, and together they have been nicknamed the "Gabriela Mistral Nebula" due to the resemblance to the Chilean poet. In this image taken with the Prompt 6 telescope at Cerro-Tololo Inter-American Observatory, you can see the bright blue stars at the center of the nebula whose stellar winds have pushed most of the remaining gas outward forming the bright red shockwave that represents the boundary between the stellar winds and the surrounding gas and dust. The hotter green area in the center is seen through emission from doubly ionized oxygen, while the shock front contains the bright pink of hydrogen alpha on the inside and the darker red of singly ionized sulfur on the outside showing that this is a region of high-density gas.
