two nebulae with stars in the center NASA, ESA, CSA, and STScI Some stars save the best for last. The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA's Webb Telescope has revealed for the first time that this star is cloaked in dust. This planetary nebula, about 2,500 light-years away and cataloged as NGC 3132, is known informally as the Southern Ring Nebula.
