Summary

Story summary

Astronomers have found a linear bar of ionized iron at the core of the Ring Nebula, about 2,570 light-years from Earth, containing roughly 14% of Earth's mass in iron and not aligned with the central white dwarf.
This finding challenges established knowledge about planetary nebulae and may change models of their symmetry.
Observations with the WEAVE instrument on the William Herschel Telescope revealed the structure, previously hidden by observational limits.
