| Astronomers find clues to decades-long coronal heating mystery Posted: 15 Oct 2013 04:16 PM PDT Scientists 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. |
