New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.

Earth's magnetic poles have reversed numerous times, a phenomenon driven by chaotic processes in the planet's outer core. Recent research suggests some reversals may have been missed, particularly ...

A new study reveals Earth's magnetic flips can last up to 70,000 years, exposing life to increased solar radiation.

The liquid outer core is surrounded by the thick layer called the mantle. It’s mostly solid rock, not melted like lava. Over time, changes in heat and pressure make the solid rock slowly flow. It’s ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

Our sun and a host of "solar twins" may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.

Over 4 billion years ago, as planets were coalescing around the newborn Sun, our star may have gone on an epic road trip across the Milky Way along with thousands of stellar "twins." And we may owe ...

Even 200 years after asteroid 16 Psyche was discovered, astronomers continue to puzzle over its formation.Psyche is the 10th-most massive asteroid in ...

Scientists are on the verge of detecting neutrinos, particles produced in supernova explosions from stars that perished ...

Our sun was born 4.6 billion years ago near the crowded center of the Milky Way and then migrated roughly 10,000 light-years ...

Beneath our homes, highways, and oceans lies a part of Earth we will never see. About 1,800 miles down, at the boundary between the molten outer core and the solid mantle, scientists have identified ...
