For two nights, dazzling auroras delighted sky-gazers in unexpected places, including in the US as far south as Florida. The cause: dual solar storms unleashed by the sun reaching Earth. A severe ...

The sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case ...

At the end of the last solar cycle in 2019, the official predictions were that the next cycle would be just as mild as its predecessor. Those predictions were wrong. The current Solar Cycle 25 turned ...

To reconstruct the Sun’s polar magnetic behavior over more than 100 years, an SwRI scientist first corrected anomalies in historical data from Kodaikanal Solar Observatory (KoSO) to sync with direct ...

The ongoing Solar Cycle 25 began in 2019 with a quieter Sun and is predicted to end around 2030. A solar cycle is roughly an 11-year period of the Sun's magnetic activity, from quiet (minimum) to ...

China is making strides in solar exploration with an ambitious plan to launch its first solar probe, Xihe-2, to the Sun-Earth L5 point. As reported by CGTN, the mission is set to take place between ...
