Solar Prominence. Searing hot loops of plasma radiate from the edge of our local star – the sun – in a phenomenon known as a solar prominence. Emanating from the sun’s outer shell, from which light is emitted, prominences extend to the corona, which is the aura of the plasma surrounding it. A typical prominence covers over thousands of kilometres, with the largest ever recorded estimated to be over 800,000 kilometres, equalling roughly the radius of the sun itself.
