Approximately 3,000 kilometres beneath the Earth’s crust lies the scorching, dynamic core—once thought to be sealed off from the rest of the planet. However, new research challenges this long-standing ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

In 2019, scientists detected a strange wobble deep below the Earth’s surface that oscillates roughly every 8.5 years. Now, by mapping minute changes in the Earth’s rotation, the team has come up with ...
