Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...

Earth formed over 4.5 billion years ago from a swirling cloud of gas and dust squished together by gravity. That same cloud gave rise to our entire solar system, including our star, the sun.

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
