Okay, so the sun isn't technically made of fire. It's an enormous ball of superheated plasma that only looks like a flaming orb — or, in the case of the above video, Sauron's eye.
In late September, a massive magnetic filament roughly 200,000 miles long burst forth from the sun's atmosphere, leaving behind what NASA dubbed a "canyon of fire."
NASA created the stunning footage by piecing together images captured by satellites over a two-day period, on September 29 and 30. The varying colors reflect different wavelengths, which are used to observe material at different temperatures — for example, the yellow images show matter at around one million degrees Fahrenheit.
