NASA gets a view of the inner workings of the Sun

NASA gets a rare view of the sun.

New technology is now allowing astronomers to begin forming hypotheses about why the sun’s outer atmosphere, called the corona, is much hotter than its surface.

NASA’s High-resolution Imager, or Hi-C, seems to have an answer. According to the U.S. space agency, energy is actively pumped to the outer parts of the sun’s atmosphere, making it hotter than areas closer to the sun, raising the atmosphere’s temperature to millions of degrees.
