USC scientists have made a groundbreaking discovery about the nature of the Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating ...

The research team used that same earthquake data for a 2024 study to resolve a longstanding debate over the inner core’s rotation. They found that the inner core once spun faster than Earth itself.

Earth Rotation Day was observed globally on Wednesday. The day celebrates the rotation of planet earth on its axis which is crucial for defining time and shape of life. Earth rotates on its axis, an ...

A recent study by American researchers indicates that the Earth’s core is not only shifting its speed but also gradually ...

This means that one lunar rotation on its axis corresponds to the time of revolution around Earth, equal to 29.5 days. On a daily basis, the moon appears to move eastward in the sky by 12°, and ...

The popular belief that European astronomy from the late Middle Ages and early Modern Age was more advanced than that of ...

The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really ...

This revelation may shed light on the mystery of why the inner core's rotation appears to have been slowing down over recent years. The Earth is made up of four main structures: the outer crust ...

In this viral video, one can see the Earth rotating. This mesmerising time-lapse video, recorded by Dorje Angchuk, an engineer at the Indian Institute of Astrophysics, Bengaluru, was shared on X. He ...
