Webb Reveals the Helix Nebula’s Eye and Its Cometary Knots
NASA's James Webb Space Telescope delivers a sharper infrared view of the Helix Nebula, the nearby planetary nebula nicknamed the Eye of Sauron, revealing about 40,000 cometary knots as the dying star sheds its outer layers. The image, updating Hubble's famed portrait, shows how the gas glows under the nebula’s radiation and how the knots persist against the expanding wind. The Helix lies ~650 light-years away and will fade over the next 10,000–20,000 years as the gas disperses, offering a glimpse of the Sun's eventual fate as a red giant that becomes a white dwarf.
