Solar flare

A solar flare that erupted on the sun this week could intensify the northern lights, and perhaps bring dazzling auroras as far south as Seattle, Chicago and Boston.

A sobering study published this month in Space Weather warns why we need to get better prepared for disruptive space weather events – particularly coronal mass ejections.

An electromagnetic pulse or a bad solar storm could possibly knock out the electrical grid, causing major problems for society.

A star smaller than Jupiter regularly fires off flares as powerful as the biggest eruptions from our sun.

The X1.2 solar flare was the fourth X-class flare in two days from the sunspot AR1748.

AR1748 should be lined up with our planet by the weekend.
