WR 102 is an extremely hot and rare type of Wolf-Rayet star in the constellation of Sagittarius. Powerful stellar winds, in combination with intense ultraviolet radiation from this very how star(surface temperature ca. 210,000 K), have compressed and ionised the surrounding interstellar material into a series of arcs and bubbles. which are depicted in the image above. Wr 102, stellar classification WO2, is one of the very few known oxygen-sequence Wolf–Rayet stars, it is highly evolved and close to exploding as a supernova. The nebulosity surrounding the star has not been named, but I feel that, at least for this interpretation the old German word for an Ant (Ameise), that is “Emse”, is somehow appropriate. The image was completed using data from a remote hosting facility in Chile.
