Scientists using sound waves to probe the interior of the Sun (in much the same way seismic waves can be used to peer inside the Earth) have now detected sunspots forming 60,000 km below the surface - almost 5 times the Earth's diameter. Two days later, the spot erupts , carrying its intense magnetic field along with it.
