Scientists Discover Earth’s Core Has Sprung A Leak 

In many ways, this recent discovery has been decades in the making. The very large ratio of helium-3 to helium-4 in Baffin Island’s volcanic rocks was first discovered by the University of Edinburgh doctoral student Solveigh Lass-Evans, and her findings were first published in 2003. 

Part of what made this discovery so exciting is that it offered more evidence for a major theory that Earth has its origins in a solar nebula that eventually collapsed because of a supernova’s shockwave. Theoretically, helium-3 was part of that solar nebula, and that is part of how it ended up in Earth’s core.
