NASA's Webb telescope captures fleeting moment of a star before going supernova

NASA's Webb Space Telescope has captured the rare and brief phase of a star in the constellation Sagittarius right before dying and going supernova.

The image, released Tuesday at the South by Southwest conference in Austin, Texas, shows the Wolf-Rayet star in unprecedented detail, casting a shimmering purple halo as it ejects gas. As the gas moves away from the star, it cools, and cosmic dust forms and glows in the infrared light detectable by Webb, according to NASA. 

"Massive stars race through their lifecycles, and only some of them go through a brief Wolf-Rayet phase before going supernova, making Webb's detailed observations of this rare phase valuable to astronomers," the space agency said in a statement.
