Understanding inner core oscillations is key to grasping Earth's rotation variations and magnetic field changes, linking deep processes to surface effects.

Context. As a star evolves, the planet orbits change with time due to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion and evaporation on/by the planet.

Variable Sun–planet magnetosphere interactions. a, Polar projections of the typical terrestrial auroral morphology from IMAGE FUV/WIC data. b,c, Saturn's dynamic auroral morphology observed by the ...

"Our study has revealed the complex interplay between solar wind and planetary rotation, providing a deeper understanding of auroras across different planets." When you purchase through links on our ...

Humanity has spent thousands of years understanding billion of years of universal history. Here’s a dizzying look at why the cosmos spin the way they do. *For the why behind this “rotation ...

Earth’s rotation is speeding up. This summer, our planet will spin faster than usual, creating the shortest day since records began. Though we cannot sense these changes, they show the forces that ...

Spring, summer, fall and winter—the seasons on Earth change every few months, around the same time every year. It's easy to take this cycle for granted here on Earth, but not every planet has a ...

The awe-inspiring aurorae seen on Earth, known as the Northern and Southern Lights, have been a source of fascination for centuries. Between May 10th and 12th, 2024, the most powerful aurora event in ...

Images from the Akatsuki spacecraft unveil what keeps Venus’s atmosphere rotating much faster than the planet itself. An international research team led by Takeshi Horinouchi of Hokkaido University ...

A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches on the star’s surface and rapid changes tied to its rotation. By combining ...
