A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches ...

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 ...

Caltech researchers have developed a new simulation of the hydrological cycle on Jupiter, modeling how water vapor condenses into clouds and falls as rain throughout the giant planet's swirled, ...

Our Moon is slowly drifting away from Earth, not just due to tidal friction as previously thought. New research suggests ancient planetary impacts and Earth's internal cooling, causing contraction and ...
