The sun is powered by the nuclear fusion of hydrogen to helium, deep within its core. Above the sun's surface, however, a different force dominates: electromagnetism. This force is responsible for ...

The Sun is now at the most active point in its roughly 11‑year solar cycle, and scientists say the current peak has arrived earlier and more forcefully than first expected. As activity climbs, ...

Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR ...

Spirals of solar wind can spin off larger solar eruptions and disrupt Earth's magnetic field, yet they are too difficult to detect with our current single-location warning system, according to a new ...

Coordinated observations between the Hubble Space Telescope and ground-based telescopes of a star that is an analogue of the young Sun have uncovered multi-temperature signatures of stellar coronal ...
