Auroras could light up skies across swaths of the planet for the second night in a row on Saturday, after already dazzling Earthlings from the United States to Tasmania to the Bahamas the day before.

The most powerful solar storm in more than two decades struck Earth on Friday, triggering spectacular celestial light shows from Tasmania to Britain — and threatening possible disruptions to satellites and power grids as it persists into the weekend.

The most powerful solar flare since 2017 has been registered so far. The sun has expelled a mass with values unseen for close to a decade, reports UPI. In less than 24 hours, the sun has unleashed three waves of X-class flares, the highest magnitude on the scale measuring the intensity of solar eruptions.

A NASA telescope has captured the biggest solar flare in years, which temporarily knocked out radio communication on Earth.

The sun spit out the huge flare, resulting in two hours of radio interference in parts of the U.S. and other sunlit parts of the world. Scientists said it was the biggest flare since 2017.
