Solar flares and other activity can disrupt radio communications, power grids and navigation signals, according to NASA.

In a series of unprecedented events, the Sun has unleashed a barrage of coronal mass ejections (CMEs), reportedly raising concerns about the resilience of Earth’s power grids and modern technology.

NASA has issued a warning that the Sun is “waking up,” with solar activity increasing steadily after decades of decline. The agency’s latest research, led by Jamie Jasinski at NASA’s Jet Propulsion ...

A powerful X1.9 solar flare from new sunspot AR4299 triggered strong radio blackouts, as giant sunspot AR4294 rotates into ...

This year has given stargazers plenty of opportunities to catch the colorful auroras of the northern lights flicker across the night sky, and that's expected to continue as the sun is now in its solar ...

The Sun follows a 22-year magnetic cycle, with solar activity rising and peaking roughly every 11 years. But when conditions ...

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 could be ...

A massive solar storm is set to cause massive blackouts across the UK and the rest of the world today after a rare ‘double punch’ from the sun. The G3 geomagnetic storm hit Earth on Tuesday, caused by ...

No, not really – but a combination of the three solar phenomena have come together in a collaboration that could produce auroras as far south as Iowa and Pennsylvania, and the north of England and ...

This year marks 30 years of SOHO observing our sun, an extraordinary milestone for a mission originally expected to last only ...

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...
