Solid Core

I know astronomy is concerned with things over our heads, but I just noticed a story concerning something in the opposite direction. It seems that seismologists have finally detected evidence for the Earth having a solid core by studying P waves from earthquakes. The research was published in the Journal, Science and shows that the solid core is very small; perhaps 1% of the volume of the planet.
