Earth's magnetic field may have been similarly as strong 3.7 billion years ago as it is today, pushing the earliest date for this planetary protective bubble back 200 million years. "When we're ...

Earth formed around 4.54 billion years ago. Knowing how old Earth is can be more difficult to confirm because Earth's age is not only based on the age of rocks, but also the isotopic estimates of what ...

Earth is some 4.5 billion years old. When it formed from colliding rocks around a dim, young sun, it was presumably lifeless, and geologists long thought that life didn’t emerge for a billion years or ...

Our Solar System is believed to have formed from a cloud of gas and dust, the so-called solar nebula, which began to condense on itself gravitationally ~ 4.6 billion years ago. As this cloud ...

We know Earth formed roughly 4.54 billion years ago and that the first single cell lifeforms were present roughly 1 billion years after that. What we don’t know is what triggered the process that ...

Long before Earth formed, tiny mineral grains were already drifting through space, forged in the final breaths of dying stars ...

Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

Remnants of a liquid layer of magma near Earth's core, formed in the first few hundred million years of the planet's history, may still persist today as odd anomalies in the mantle. When you purchase ...
