Primordial Helium From Billions of Years Ago Seems to Be Leaking Out of Earth's Core


Michelle Starr - Yesterday 11:39 PM

Ancient, primordial helium that was forged in the wake of the Big Bang is leaking from Earth's core, scientists report in a new study.

There's no cause for alarm. Earth isn't deflating like a sad balloon. What it does mean is that Earth formed inside a solar nebula – the molecular cloud that gave birth to the Sun, a detail about our planet's birth that has long been unresolved.

It also suggests that other primordial gases may be leaking from Earth's core into the mantle, which in turn could yield information about the composition of the solar nebula.

Helium on Earth comes in two stable isotopes. By far the most common is helium-4, with a nucleus containing two protons and two neutrons. Helium-4 accounts for arund 99.99986 percent of all the helium on our planet.

An extremely rare type of helium that was created soon after the Big Bang is leaking out of Earth's metallic core, a new modeling study suggests.

The vast majority of this gas in the universe, called helium-3, is primordial and was created just after the Big Bang occurred about 13.8 billion years ago. Some of this helium-3 would have joined other gas and dust particles in the solar nebula — the vast, spinning and collapsed cloud that is thought to have led to the creation of the solar system.

The discovery that Earth's core likely contains a vast reservoir of helium-3 is further evidence to support the idea that Earth formed inside a thriving solar nebula, not on its periphery or during its waning phase, the researchers said.

Helium-3 is "a wonder of nature, and a clue for the history of the Earth, that there's still a significant amount of this isotope in the interior of the Earth," study lead author Peter Olson, a geophysicist at the University of New Mexico, said in a statement.
