team of researchers Recently explained that thing more than 1.8 kilo Helium-3 escapes the Earth every year, and it’s obvious An indication that our planet formed in a solar nebula.

Helium-3 is a very old isotope of the gas. helium; sAlmost all helium-3 originated with The Big Bang, though some also come from the radioactive decay of tritium. But Primordial helium-3, the material from which it was made After the Big Bang, it ended up in clouds of gas and dust called nebulae, who then gave him The origin of stars like our sun, of course Planets like Earth.

The team studied the rate at which this primordial gas escaped from Earth through its mantle and used it to estimate the total amount of the isotope that might still be present in our planet’s core. was his research published This week in the scientific journal Geochemistry, geophysics and geological systems.

It is one of the wonders of nature, and evidence of it Peter Olson, a geophysicist at the University of New Mexico and lead author of the book said:Is the new studio, in a release. Olson added that around her 2000 grams of helium-3 that escapes from the planet each year ‘enough to Fill a balloon of size tU office.”

The theory The solar nebula was probably the most widespread when our solar system appeared. Basically one cloud of floating matter So intense that it ended up forming The sun and planets in a period of time Billions of years. Olson’s team explained that most Helium 3 that is leaking comes from my back peripheral. researchers cRevisit that 3-inch helium Our core The accretion of the planet when the Earth was in the early stages of its formation.

Researchers are still not sure how much helium-3 was captured really in Essence when Formed and how many expelled since then. If researchers find other gases associated with nebulae, such as hydrogen, that are emitted from Earth at similar locations and speeds as Helium-3, that would be a telltale sign that the core is, in fact, where the helium is hiding.

In total, the team calculated that there could be between 10 tg (1 million metric tons) and a petagram (billion metric tons) of helium-3 in the core. It is very wide rangeFor now, Olson indicated in the statement “There are many more mysteries than certainties.”

However, regardless of the actual quantity, the helium leakage corresponds to solar nebula theory
