 Sometimes, you just need to give your mind a little vacation. And these days, outer space sounds like as good a destination as any. Thankfully, the James Webb Space Telescope (JWST) is here to give us a dazzling new image of the Helix Nebula.
Discovered in the early 19th century, the Helix Nebula resides in the constellation Aquarius. (Cue The 5th Dimension.) At about 655 light-years away, it's one of Earth's closest planetary nebulae. When zoomed farther out, it's easy to see why it's been nicknamed the Eye of God or Eye of Sauron. This 2004 image from the Hubble telescope illustrates that.

Bacon ( STSI)What we're seeing in the nebula is, in a sense, a moment of death that lays the groundwork for a new birth. The dying star (out of frame in the closer new image) sheds its outer layers. As expelled gas and dust cool, they provide raw material that could someday form new stars and perhaps planetary systems.
The new image from Webb's NIRCam (Near-Infrared Camera) provides a much closer, higher-resolution view.
