Story summary

Researchers at the University of Hawai'i's Institute for Astronomy report that coronal rain can condense in just 35 minutes.
The study shows coronal rain is influenced by shifting flows of iron and magnesium, rather than a constant elemental distribution.
The research is published in The Astrophysical Journal.
The findings prompt a reevaluation of coronal heating mechanisms and advance understanding of the Sun's cooling processes.
