This photo , take last workweek by NASA ’s Solar Dynamics Observatory ( SDO ) , shows a “ filament ” of cool solar material hover over the surface of the sun . The effect is of a huge crack across the sun , as if something is preparing to burst out .

NASAexplains :
SDO show colder cloth as dark and hot material as luminousness , so the line is , in fact , an tremendous swatch of cold material hovering in the Sunday ’s atmosphere , the corona . stretch along out , that line – or solar fibril as scientist call it – would be more than 533,000 international mile long . That is longer than 67 Earths lined up in a course . Filaments can float sedately for day before disappearing . Sometimes they also erupt out into blank space , releasing solar stuff in a shower that either rain down back down or escapes out into blank space , becoming a moving swarm known as a coronal volume forcing out , or CME . SDO captured images of the filament in numerous wavelength , each of which helps highlight material of dissimilar temperatures on the sun . By reckon at such features in unlike wavelengths and temperature , scientist learn more about what stimulate these structures , as well as what catalyzes their casual eruptions .
