Meteor showers are about persistence, but they're also about luck. The camera gives you coverage — a way to stack the odds — ...

HEFEI -- Chinese and international scientists have, for the first time, discovered a solid inner core, with a radius of about 600 km, inside Mars, thereby providing crucial clues to the evolutionary ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. New research shows that rising sea levels caused by melting ice sheets are redistributing mass across the planet, ...

The new study described this "almost unprecedented rate of increase" in the length of an average day as a quantifiable consequence of Earth's rising oceans. Reading time 3 minutes It often feels like ...

Rising sea levels are slowing Earth’s rotation, lengthening how long an average day lasts. And the current rate of increase to a single average day—1.33 additional milliseconds per century—is ...

Here’s what you’ll learn when you read this story: Where Earth got most of its water is a subject of debate, but a new study suggests that the planet’s largest reservoir of hydrogen is not the ocean, ...

A study published this week in Nature Communications posits that Earth's core holds a lot of hydrogen. The range is from nine to 45 oceans' worth of hydrogen, mostly locked up in the form of iron ...

Two vast, mysterious blobs of hot rock around Earth’s core may have been instrumental in producing Earth’s magnetic field and caused it to be slightly wonky for millions of years. Scientists have ...

Earth's core is mostly made of the metals iron and nickel, but it also contains lighter elements like hydrogen, oxygen and silicon. CharlesC via Wikimedia Commons under CC-BY-3.0 How Earth got its ...

It’s not hard to see why there are so many conspiracy theories about what lies beneath our feet. The surface of the Earth – the crust – on which we live makes up a mere one per cent of the planet’s ...

LONDON — Picture all of Earth's oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth's core, possibly ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...
