Our Sun. It's a dynamic place. Here, is a computer model that generates a view of the Sun's magnetic field, allowing scientists to better monitor active regions and understand how solar material courses around the Sun's surface. Using real-time data taken from our Solar Dynamics Observatory on August 10, 2018, we see a bright active region right at the central area of the Sun. It 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.

The observatory helps us understand the Sun's influence on Earth and near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.
