Some 4.6 billion years ago, Earth was nothing like the gentle blue planet we know today. Frequent and violent celestial impacts churned its surface and interior into a seething ocean of magma—an ...

Scientists have confirmed that a tiny zircon crystal is the oldest piece of the Earth's crust, at 4.4 billion years old. The crystal was discovered on a sheep ranch in Perth, Australia in 2001, but ...

Just over 4 billion years ago, magma from Earth’s mantle infiltrated a fracture in the young planet’s primordial crust. Over the following aeons, nearly all of the planet’s early crust melted back ...
