Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

Critics loved new dramas like "Heated Rivalry" and "Pluribus," but series like "All's Fair" were some of their least favorite ...

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in surprising and fascinating ways.

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird ...

The War Between the Land and the Sea is a spin-off from Doctor Who while also very much its own story. Kevin Hilton talks to ...

For more than a decade, NASA’s Cassini spacecraft traced Saturn’s rings and moons, returning some of the most detailed ...

For more than a decade, scientists have accepted that Titan, Saturn’s biggest moon, has a subsurface ocean of liquid water. A new look at the data suggests otherwise.

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

New research suggests that during Earth’s earliest, hottest phase, vast amounts of water may have been stored deep within the mantle rather than lost to space. A key mantle mineral appears to have ...
