Webb reveals a planetary nebula with phenomenal clarity, and it is spectacular
The colors show the star’s final breath transforming into the raw ingredients for new worlds.
TL;DR
- The Helix Nebula, often called the "Eye of Sauron," is a planetary nebula approximately 655 light-years from Earth.
- The James Webb Space Telescope has released new images of the Helix Nebula.
- The images show vibrant pillars of gas along the inner region of the nebula's expanding shell.
- A white dwarf star at the nebula's heart emits radiation that lights up the surrounding gas.
- Different colors in the Webb image represent gas temperature and chemistry, with blue indicating the hottest gas and red the coolest.
- The nebula's composition includes hot ionized gas, cooler molecular hydrogen, and dust clouds where complex molecules can form.
- This process is seen as the raw material for the potential formation of new planets in other star systems.
