Summary

Story summary

A recent study of interstellar comet 3I/ATLAS tracked atomic nickel and iron emissions before and after its closest solar approach, advancing ideas about planet formation.
The researchers found that the outer layers are sun-baked, complicating efforts to determine the comet's original composition.
Despite this, the data enhance knowledge of cosmic origins and the processes shaping planetary systems.
The findings connect our solar system to the broader cosmos and inform models of how materials become part of planets.
