The sun’s wispy upper atmosphere, known as the corona, is an at any time-altering jungle of scorching plasma. But mapping the energy of the magnetic fields that largely control that conduct has proved elusive. The fields are weak and the brightness of the sun outshines its corona.
Now however, observations taken using a specialized instrument termed a coronagraph to block out the sun’s shiny disk have permitted photo voltaic physicists to evaluate the velocity and depth of waves rippling via coronal plasma (SN: 3/19/09). “This is the to start with time we’ve mapped the coronal magnetic discipline on
