While parallel universes are a staple of science fiction, there are some real scientific theories to support them. But if parallel universes do exist, could we ever travel to them? It certainly ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the ...

A "super-Earth" planet found outside of our solar system could have conditions suitable for life, according to experts at the University of Oxford. Researchers said the planet has a mass six times ...

Here’s how it works. Scientists have captured magnetic signatures from Earth's ocean tides in the finest detail yet. These faint signals, which certain satellites can detect when flying at very ...

This new model updates the location of magnetic north while also providing improved navigation for technologies reliant on Earth’s magnetic field. Updated every five years, scientists have ...

Earth has its fair share of fleeting companions. But sometimes, these so-called “mini-moons” have a surprising origin story. Take 2024 PT5, a bus-sized asteroid that drifted near Earth last year.

The near-Earth object may have been ejected to space following an impact thousands of years ago. NASA/JPL-Caltech For a brief, but exciting, time last year, Earth had two moons. A small asteroid ...
