Astronomers have just released the highest-resolution images ever taken of the Sun's corona, or million-degree outer atmosphere, in an extreme-ultraviolet wavelength of light. The 16-megapixel images were captured by NASA's High Resolution Coronal Imager, or Hi-C. The Hi-C telescope provides five times more detail than the next-best observations by NASA's Solar Dynamics Observatory.
