The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, ...

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 ...

An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.

A powerful flare unleashed a severe solar storm that caused auroras and GPS disruptions on Earth.

Research conducted by an international team of astronomers from Southwest Research Institute, Aryabhatta Research Institute ...

NASA has selected a proposed solar mission for further study as part of its Small Explorer programme, extending early design ...

Largest solar radiation storm in more than 20 years could trigger auroras on Earth - A solar radiation storm this large has ...

HOUSTON—Solar activity—thought to rise and fall over 11 year cycles—has been on an incline since 2008, a NASA Jet Propulsion Laboratory (JPL)-led study says. The study points to an uptick in space ...
