NASA has released an amazing close-up photo of the sun showing the aftereffects of a solar filament eruption on the sun. The photo was taken in late September and according to NASA, the erupted filament was actually 200,000 miles long. The “canyon of fire” you see here is what it left behind on the sun’s atmosphere.
“The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields,” NASA explained on the website page.
