The Sun As Art
Solar corona in high resolution
01/28/13

 

This is one of the highest-resolution images ever taken of the solar corona, or outer atmosphere. It was captured by NASA's High Resolution Coronal Imager, or Hi-C, in the ultraviolet wavelength of 19.3 nanometers. Hi-C showed that the Sun is dynamic, with magnetic fields constantly warping, twisting, and colliding in bursts of energy. Added together, those energy bursts can boost the temperature of the corona to 7 million degrees Fahrenheit when the Sun is particularly active. Credit: NASA
