Today’s Sun, seen through a filter of ‘visible’ light (remember: NEVER look directly at the Sun!), as viewed by the Solar Dynamics Observatory (SDO), by the Helioseismic Magnetic Imager (HMI). This image is known as a ‘continuum’ image; a continuum image is formed by filtering portions of the visible light part of the spectrum. The SDO HMI is designed to study oscillations and the magnetic field at the solar surface, or photosphere.
The continuum images allow us to track the evolution of sunspots. These images are important as they allow us to better understand the dynamic nature of the solar atmosphere.
