There are many lesser-known facts about the planet Earth, but one thing we know for sure is that it's a geoid - a roughly ellipsoidal shape. However, flat-earthers have been trying (and failing) to ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests could have quickly formed in the presence of compounds called borates. When ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

Scientists used a new technique to estimate the abundance of hydrogen in Earth’s core. - Tumeggy/Science Photo Library RF/Getty Images Picture all of Earth’s oceans, which cover about 70% of the ...

This approach relies on assumptions about how atoms are arranged in Earth’s core and how silicon, oxygen and hydrogen disperse there, Huang said. Their experiments revealed how hydrogen interacted ...
