A Wolf-Rayet Star
“Approaching the Wolf-Rayet star WR 102. The blue-white hot core ejects matter at 5000 km/s in vast stellar wind cavities, expanding shells of glowing helium and nitrogen form a nebula around the star, an asymmetric outflow shapes a bipolar structure, the local interstellar medium is bow-shocked by the wind, and the star nears the end of its life.”
