NASA scientists have expressed concern after detecting an unexpected surge in solar activity, reversing decades of decline in sunspots and solar wind. The discovery suggests the Sun is entering a more active phase than experts had anticipated.
The change could have far-reaching consequences on Earth, from interruptions to satellites, power grids and radio systems to more frequent sightings of the Northern Lights at latitudes much further south than usual. For people in the UK, this may mean auroral displays visible in northern England and Scotland, making a rare natural spectacle more common.
