Scientists studying Earth's magnetic field have discovered that its electric heartbeat flows in the opposite direction from what long-standing models predict. Earth is surrounded by a vast magnetic bubble called the magnetosphere,

The asteroids are as large as around 75 and 91 feet in diameter, according to the Center for Near Earth Object Studies.

Astronomers recently detected a stray quasi-moon in our planet’s orbit, but it's hardly the first stowaway to hang out around Earth.

The planet’s long-standing natural “thermostat” is being outpaced by an feedback loop process involving algae, phosphorus, and oxygen that’s supercharged by anthropogenic climate change.

The sun has burped out bursts of energy called coronal mass ejections that could reach Earth Tuesday night. Forecasters said the vibrant displays could be visible across much of the northern U.S.

Scientists have discovered a fern from South China that naturally forms tiny crystals containing rare earth elements (REEs). This breakthrough opens the door to a promising new way of "green mining" of these minerals called phytomining.

The US and China are still negotiating over the key details of how Beijing will free up sales of rare earths, according to a person familiar with the matter, weeks after a trade truce that Washington said would pave the way for increased exports.

Global supplies of the rare earth element yttrium are running low due to Chinese export restrictions, sparking fears of shortages and surging costs that could hit aerospace, energy and semiconductor production.
