The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed ...

Different stars can exhibit different levels of activity. The Sun's signs of solar activity are rather feeble on an astronomical scale. Other stars are up to ten times more active. While researchers ...

Image of the Sun taken from the Solar Dynamics Observatory satellite, showing the quiet corona and magnetic structures like coronal loops, which trace the intricate patterns of magnetic field lines ...

For decades, scientists have pondered the mystery of the moon’s ancient magnetism. Based on analyses of lunar samples, its now-deceased magnetic field may have been active for more than 1.5 billion ...

A long discussed theory about the local magnetic spots of the moon suggests that they are the result of magnetization processes caused by impacts of massive bodies on the moon surface. A new study now ...

The mystery of why Mercury's magnetic field is so weak may just have been solved: It is being stifled by the solar wind, researchers think. Mercury and Earth are the only rocky planets in the solar ...
