While we might think of these as the major features of a volcano, there's often a magnificent visual sight that accompanies these: volcanic lightning. Although not every eruption will produce this stunning light show, it's been observed and recorded by humans for countless generations. Now, with our advanced understanding of physics and the physical sciences, we finally understand how it's produced. Pockets of magma exist deep within the Earth’s mantle, originating as deep as...
