Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – raising big questions about how long these reversals actually take, and how we ...

The Earth is apparently halfway through its lifecycle, and this was revealed using an unlikely neighbour in space – and it ...

With an estimated 6 sextillion kilograms of the stuff—that’s 21 zeroes by the way—the Earth’s core is another example of why hydrogen is the most abundant element in the universe.

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Earth’s continents are not fixed in place. They drift, collide, and break apart over hundreds of millions of years, and new ...

Planet Earth is spinning a little faster today — resulting in one of the shortest days of the year. But the change will be so minuscule you won’t even notice. We’re talking even less time than the ...

Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a major storage place for hydrogen, possibly equivalent to dozens of oceans’ ...

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...
