For many years now, the activity of the Sun’s 11-year solar cycle has been gauged through visible indications like sunspots, solar activity, magnetic fields, and radio waves. Yet according to recent ...

NOAA data confirm Solar Cycle 25 is entering its declining phase after peaking higher and faster than expected, but scientists warn that the risk of extreme geomagnetic storms remains high. Historical ...

Internal changes due to the Sun’s ‘active biorhythm’ have become increasingly ‘skin-deep’ over the past four solar activity cycles, according to a new study. Publishing its findings today (28 May) in ...

A spacecraft image shows the Sun as a patchwork of yellow and black. Many thin, white arcs extend away from the brighter yellow patches on the Sun and loop back downward to other parts of the Sun.

Scientists studying 50 years of solar data warn Earth may be entering a heightened risk period for rare “superflares” capable of disrupting technology worldwide.

An international team led by Professor Tian Hui from Peking University has recently measured the global magnetic field of the solar corona for the first time. The team used observations from the ...
