A new study has found that a huge chunk deep underground in Hawaii appears to be solid and rich in iron.

Earth is ‘missing’ lighter elements. They may be hiding in its solid inner core.

For close to a century, geoscientists have pondered a mystery: Where did Earth’s lighter elements go? Compared to amounts in the Sun and in some meteorites, Earth has less hydrogen, carbon, nitrogen and sulfur, as well as noble gases like helium — in some cases, more than 99 percent less. Some of the disparity is […]
