Ancient helium that became trapped in Earth’s core when our planet formed billions of years ago may be leaking from lava flows, according to researchers.

Scientists discovered the true age of Earth's core, and it's older than they thought. Over the years, approximations for our planet's inner core have been all over the board, but most recently ...
