X9 solar flare launched from sun is the biggest in 7 years — and Earth is in the firing line (again)The sun has unleashed the most powerful solar flare since 2017, just days after it spat out another monster explosion. Both outbursts have launched solar storms that will likely hit Earth this weekend and trigger vibrant aurora displays.

'We'll be studying this event for years': Recent auroras may have been the strongest in 500 years, NASA saysVibrant auroras that were recently observed by millions of people across the globe were some of the most widespread in the last five centuries, NASA says. The light shows may have also reached the equator.
