A battle of forces, driven by the motion of Earth’s core, can explain small variations in the planet’s rotation, study finds.

The Earth's inner core seems to be solid. But what shape is it?”I started investigating from that simple question.Is it a ...

Earth's inner core swings about 2.35 degrees over roughly 70 years, and its gravitational pull changes the length of a day by ...

We use a day as 24 hours. When we look at a clock, it feels as though time from morning to night progresses at a constant ...

Earth's core holds far more gold than anyone can reach. More than 99.999 per cent of the planet's stores of gold and other precious metals lie buried under 3,000 kilometres of solid rock, locked away ...

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 ...

Earth’s days are not always exactly 24 hours long. Tiny changes in the planet’s rotation can add or shave off a few ...

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, ...

Deep beneath our feet, a slow trickle of gold is escaping from the heart of Earth. That is the striking conclusion of a new study that used ultra-precise chemical fingerprints in Hawaiian lava to show ...
