Magnetic Field Portrayed

Aug. 14, 2018
NASA's Solar Dynamics Observatory scientists use their computer models to generate a view of the sun's magnetic field. An extreme ultraviolet view of the sun is compared with the same image showing the superimposed field lines on August 10, 2018.

NASA's Solar Dynamics Observatory (SDO) scientists use their computer models to generate a view of the sun's magnetic field (Aug. 10, 2018). We took the opportunity to compare an extreme ultraviolet view of the sun with the same image showing the superimposed field lines. The bright active region right at the central area of the sun clearly shows a concentration of field lines, as well as the small active region at the sun's right edge, but to a lesser extent. Magnetism drives the dynamic activity near the sun's surface.

SDO is managed by NASA's Goddard Space Flight Center, Greenbelt, Maryland, for NASA's Science Mission Directorate, Washington. Its Atmosphere Imaging Assembly was built by the Lockheed Martin Solar Astrophysics Laboratory (LMSAL), Palo Alto, California.
