New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.
Tidally locked planets always present the same face to their host stars. What does this mean for their potential to support life?
Some exoplanets orbit their stars from pole to pole instead of across the equator. Why do they do that?
Venus’s heavy atmosphere tugs the planet’s surface enough to change the length of its day by up to 21 minutes.
Chemical compositions of rocks from Mars indicate that the earliest orbits of Jupiter and Saturn were more circular than they are today.
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.
Thanks to spectacular high-resolution images from Hayabusa2, scientists can now better estimate how and when the asteroid Ryugu formed, how its orbit has changed over time, and what its surface looks like.
A new modeling study shows how the density of the thermosphere influences the paths of satellites in low Earth orbit.
Flexible definitions of the word “climate” may impede policy discussions on climate change. Closing apparent gaps between “climate” and “weather” may help reduce the ambiguity.
In the most detailed and highest-resolution black hole simulation to date, an international team of researchers showed the Bardeen-Petterson effect for the first time.
