Located around 8000 light-years away in the constellation of Scorpius (The Scorpion), NGC 6357 -- sometimes nicknamed the Lobster Nebula due to its appearance in visible-light images -- is a region filled with vast clouds of gas and tendrils of dark dust. These clouds are forming stars, including massive hot stars which glow a brilliant blue-white in visible light.
