Webb telescope exposes Helix Nebula’s comet-like knots in sharp relief
NASA's JWST has released a high-resolution image of the Helix Nebula, revealing its comet-like knots formed as a dying star sheds its outer layers. The new NIRCam view shows hotter blue gas near the core and cooler dust at the edges, offering our closest, sharpest look at this ~655-light-year-away planetary nebula and illustrating how stellar death seeds new star formation.
