PHOTO OF DAY: Stunning Solar Activity Caught By NASA Shows Towering Loops

By  //  July 20, 2015

viewed in extreme ultraviolet light

A whole series of loops towered above a group of active regions over a five-days period (July 9-13, 2015). When viewed in extreme ultraviolet light, magnetic field lines above the Sun's surface are revealed by charged particles that spin along the lines and create these loops. They are best observed along the edge of the Sun as they are here. The tallest of the loops reach up about 15 times the diameter of Earth. (Solar Dynamics Observatory, NASA image)
