The mineral is „djerfisherite, a potassium‑bearing iron‑nickel sulfide, embedded in a grain from the carbon‑rich C‑type asteroid“
For those who want the quick answer that the clickbait title doesn’t provide.
The element is djerfisherite, a potassium-containing iron-nickel sulfide, in a Ryugu grain.
Why unexpected:
Djerfisherite is a mineral that typically forms in very reduced environments, like those found in enstatite chondrites, and has never been reported in CI chondrites or other Ryugu grains.
Its occurrence is like finding a tropical seed in Arctic ice—indicating either an unexpected local environment or long-distance transport in the early solar system
