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

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.

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.

Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ice ages and warm climates, new research finds.

The sun sure has woken up this week, unleashing a powerful X-class solar flare on Jan. 18 that hurled a colossal, fast-moving coronal mass ejection (CME) directly toward Earth. That CME has now arrived, triggering severe (G4) geomagnetic storm conditions far earlier than initially forecast.

The far-flung “Project Anchor” conspiracy theory claims that NASA is preparing for Earth to “lose” gravity on August 12, 2026, is circulating on social media.

With a synchronized tap from run-of-the-mill hammers on metal plates resting on the ground, researchers kneeling in nine fields across four continents believe they’ve hit upon more than just the earth beneath their feet.

The CME was launched during a powerful X-class solar flare on Jan. 18 and raced toward Earth at speeds of 620–870 miles per second (1,000–1,400 km/s). Aurora chasers, get those camera batteries charged and your alerts switched on — tonight could be quite the night.
