When a 200,000-mile (320,000-kilometer) filament of solar material tore through the sun last month, it
cut what looks like a "canyon of fire" in our closest star, new NASA observations show.
Researchers at the Goddard Space Flight Center in Greenbelt, Md., pieced together a video of the sun's fire "canyon" of the phenomenon based on images collected on Sept. 29 and 30 by the space agency's sun-watching Solar Dynamics Observatory. | Space.com

- Astronomers find clues to decades-long coronal heating mystery
Drs. Michael Hahn and Daniel Wolf Savin, research scientists at Columbia University's Astrophysics Laboratory in New York, NY, found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona and moreover that they also deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona. The observations help to answer a 70-year-old solar physics conundrum about the unexplained extreme temperature of the Sun's corona – known as the coronal heating problem.
