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 ...

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.

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 ...

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

New potential climate crisis just dropped.

Where did all the water come from? Water, water everywhere. It covers 70 percent of Earth’s surface and earns it the nickname “the blue planet.” And yet… where did it come from? How is it so abundant ...

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, ...

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

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

Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger ...
