First identified in the early 1800s, the Helix Nebula is one of the most recognizable planetary nebulas in the night sky, known for its dramatic ring-like appearance. Because it is one of the closest planetary nebulas to Earth, astronomers have long used both ground-based and space-based telescopes to study it as a detailed example of how stars end their lives.

Those observations have now reached a new level with the James Webb Space Telescope, which has delivered the clearest infrared view yet of this well-known object.

A Glimpse of the Sun’s Distant Future
Webb’s powerful instruments allow scientists to zoom in on the Helix Nebula and examine what could one day happen to our own Sun and planetary system. The telescope’s high-resolution data brings the structure of gas streaming away from the dying star into sharp focus. These observations show how stars return their material to space, providing the ingredients that later form new stars and planets.

Images captured by Webb’s NIRCam (Near-Infrared Camera) reveal striking pillar-shaped features around the inner edge of an expanding shell of gas. These structures resemble comets with long tails pointing away from the central star. They form where intense winds of hot gas collide with cooler layers of dust and gas that were released earlier in the star’s life, carving the nebula into its complex and textured shape.
