Coronal Hole

July 22, 2013
The European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO, captured this image of a gigantic coronal hole hovering over the sun’s north pole on July 18, 2013, at 9:06 .a.m. EDT. The image shows light in the 284 Angstrom wavelength, which highlights hotter solar material, so thecolder coronal holes stand out in dark relief.
