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.

Leonardo Testi and team investigate the initial conditions for planet formation in this special astronomy focus ...

Visualizing our solar system is one of those third-eye treats that never grows old. The Sun and its gravitationally bound planets, asteroids, etc. are in constant relative motion, and thinking about ...

The Coriolis effect impacts global patterns and currents, and its magnitude, relative to the magnitude of inertial forces, is expressed by the Rossby number. For over 100 years, scientists have ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Venus’ rotation has always been weird. While it completes an ...

Time is out of joint on Venus. The planet’s thick air, which spins much faster than the solid globe, may push against the flanks of mountains and change Venus’ rotation rate. Computer simulations show ...

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 ...
