Sun unleashes powerful X2-class flare (video)

The sun blasted out a superpowerful X-class flare on Friday afternoon (March 3), and a NASA spacecraft captured footage of the dramatic event.

The solar flare — an intense burst of high-energy radiation — erupted Friday at 12:52 p.m. EST (1752 GMT). It registered as an X2.1, NASA officials said (opens in new tab), meaning it was particularly intense. (Solar scientists categorize potent flares into three categories, with C being the weakest, M being medium-strength and X the most powerful.)
