The rare sight of a Wolf-Rayet star — among the most luminous, most massive, and most briefly detectable stars known — was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.
