Scientists uncover how a new exoplanet changes its host star's chemistry and magnetic behavior in twin-star systems, offering insights into planet formation and stellar evolution. The post New ...

A new study published in Nature Astronomy, led by Dr. Jie Yu, from the Australian National University, reveals that stars in ...

It seems that the solar cycle of magnetic activity is meddling with their efforts. Of course, we can verify the sun's true age through independent means — and we therefore know it's about 4.6 ...

Large and complex sunspot groups characterize the surface of the dynamic sun during its activity cycle. A new camera system at the Vacuum Tower Telescope (VTT) at the Observatorio del Teide on ...

The sun, and the intense magnetic activity it generates that causes the northern lights, waxes and wanes on an 11-year-long solar cycle that is at its maximum. Because NASA anticipates the solar ...

This approximately 11-year cycle of solar activity is driven by the sun's magnetic field and is measured by how frequent and intense the sunspots visible on the sun's surface are. When solar ...
