Iron is usually among the most abundant elements in soils, and it is a linchpin of chemical cycling in the environment.

Stars are like onions. Onions have layers; stars have layers. You get it? They both have layers.

Happy Equinox, from Eos! Today, Earth’s axis is tilted neither toward nor away from the Sun, meaning the Sun’s direct rays fall on the Equator. Depending on which hemisphere you inhabit, today is either the first day of fall or the first day of spring! Image credit: NOAA

Water constraints are leaving more fallowed fields in California’s Central Valley. New research shows these unplanted lands are linked to a rise in dust storms, which can cause traffic, healthy, & environmental impacts. buff.ly/Ui5RN3U Read more: bit.ly/Eos-Sept2025

My favorite thing about exoplanet research is how much weirder the Sol system gets every time we get more data. We can't see small planets still and we're only scratching the surface, but our solar system really does seem to be a bit of an odd one

Using iron-57 tracers could help in studies of geological processes on Earth or other astronomical bodies such as Mars. And many potential applications exist outside the Earth sciences as well.

“These numbers represent real people who have lost their lives in the last months due to extreme heat,” said Friederike Otto, a climatologist at Imperial College London's Centre for Environmental Policy. “Many of these would not have died if it wasn’t for climate change.”

A planet more massive than Mercury could be lurking beyond the orbit of Pluto, but don't call it Planet X.

To learn more about how Earth’s climate might change, scientists looked 10 million years into the past.
