This week, we examine strength from different perspectives. The energetic strength of a solar flare and its effect on Earth. The gravitational strength of dark matter in our universe and its ...

India's space agency ISRO is closely watching intense solar flares. These powerful bursts from the Sun can cause radio ...

The Sun has entered one of its most volatile moods in years, hurling a torrent of powerful flares and charged particles into ...

Multiple M-class and X-class solar flares erupted within 24 hours as an active sunspot released intense radiation affecting Earth’s upper atmosphere and radio communications.

Space weather has seen a flurry of activity this week. An explosive solar flare that erupted Tuesday, just two days after the sun unleashed one of its most powerful flares, temporarily disrupted ...

Scientists monitor an unusually active sunspot as powerful solar flares erupt, raising questions about causes, cycles, and ...

Something stormy is happening in the skies right now. The sun has released a “relentless barrage” of solar flares (21 overall) in the space of 24 hours, Space reports – and it seems more could be on ...

The X8.1 flare was accompanied by a coronal mass ejection (CME), a significant release of plasma and magnetic field from the sun's corona. Modeling suggests that the bulk of the material from this CME ...
