308

Astronomy enthusiasts are sharing images and details of Sh2-308, the nebula nicknamed the Dolphin Nebula. Located about 5,000 light-years away in the constellation Canis Major, the vast cosmic bubble spans roughly 60 light-years and was shaped by the intense radiation and stellar winds of a massive Wolf-Rayet star. Posts highlight its striking shape and the dramatic process by which a dying giant carves such an enormous structure into surrounding gas.
