"This is the largest solar radiation storm in over 20 years," the Space Weather Prediction Center said on Monday.

The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing their thick atmospheres.

A powerful flare has unleashed a severe solar storm that could cause auroras and satellite disruptions on Earth.

Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods and warm "greenhouse" states.

Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position from the sun. Without it, life could potentially have been a lot different from what we know today.

Although 2025 did not set a new global temperature record, it still delivered clear signs of a warming planet.

Trump’s push to break that chokepoint is lifting rare-earths startups. Phoenix Tailings, a startup focused on recycling mining byproducts into rare-earth minerals, added $33 million to its Series B in 2025, bringing its funding round total to $76 million.

Earth is still reverberating from the colossal coronal mass ejection ( CME) that struck on Jan. 19, triggering dazzling aurora displays worldwide. And while tonight's show (Jan. 20) may be somewhat more subdued, the solar storm isn't quite over — so keep your camera batteries charged and your aurora alerts on.
