Solar activity waxes and wanes on an 11-year cycle.The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say.

The recent flurry of solar storms suggests the sun is in a period of maximal activity as part of its 11-year cycle. The active period is likely to continue over the next year, so more auroras ...

The solar cycle typically spans about 11 years, with the sun going from a quiet period of low magnetic activity to a highly active phase characterized by intense solar flares and solar storms.

But the sun had been primed to put on a show as it approached the maximum phase of its 11-year activity cycle—and that high activity continues today. This solar cycle still has the potential to ...

Solar Orbiter is currently collecting information on several solar phenomena, including the sun’s magnetic field, its activity cycle, and the solar wind – a constant, high-speed stream of ...

Solar Orbiter is gathering data on phenomena including the sun's magnetic field, its activity cycle, and the solar wind, a relentless high-speed flow of charged particles emanating from the sun's ...

The sun’s behaviour fluctuates on an 11-year solar cycle during which the sun’s magnetic field reverses its polarity, when the two magnetic poles switch over. There are two main phases in the ...
