Astronomers using NASA’s Hubble Space Telescope have measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the ...

The Sun serves as a natural reference for the modelling of the various physical processes at work in stellar interiors. Helioseismology results, which inform us on the characterization of the interior ...

There is interesting new work from Cool Worlds. A quasite is a conceptual space-based satellite system proposed by the Cool Worlds Lab (led by astronomer David Kipping), representing a hybrid or ...

Our result has implications for our understanding of the solar dynamo. First, the small-scale magnetic fields, which act as the driving force of the height-dependent solar rotation, are probably ...
