Title:[0230] A Wolf-Rayet star in NGC 2359 Caption:Wolf-Rayet stars are massive, extremely hot stars ejecting material from their seething surfaces with velocities of thousands of kilometers per second. In the case of NGC 2359, the stellar wind is interacting with the gas and dust around the star producing the cosmic bubble seen here. The shell-like layers are formed by a single star, HD 56925, shedding a substantial fraction of its outer substance into a part of our Galaxy rich in interstellar gas. Such stars are unusual, mainly because extreme behavior of this kind cannot be sustained for long. Copyright:(c) 1979 Anglo-Australian Telescope Board, photograph by David Malin Credit:D. F. Malin
