NASA has compiled a new video showing a 200,000-mile-long “fire” as it rips across the surface of the sun in dramatic fashion.
The eruption is actually a magnetic filament of solar material that erupted across the atmosphere of the sun back in September. The resulting corona appears to be a giant canyon of flames.
NASA physicist David Hathaway explained in an interview with Space Weather that a magnetic filament actually contains cool, dense gas that is suspended above the surface of the sun.
"When you look down on top of them they appear dark because the gas inside is cool compared to the hot photosphere below,” Hathaway said. “But when we see a filament in profile against the dark sky it looks like a giant glowing loop -- these are called prominences and they can be spectacular."
As NASA explained on their Goddard Space Flight Center YouTube page, “In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creatingRead More »from Watch an enormous 200,000-mile canyon fire race across the sun (VIDEO)
