Earth’s magnetic field sustains life on our planet, protecting us from solar winds, radiation and extreme changes in temperature. But around 591 million years ago, it almost collapsed.

The planet's magnetic field may have collapsed around 600 million years ... suggests that Earth's magnetic field underwent a major weakening about 591 million years ago. This corresponds to ...

As per the theory, between 720 to 635 million years ago, Earth's climate was radically altered due to a combination of events. As a result, temperatures all over Earth plummeted, and thick ice ...

From 3 billion years ago to roughly 600 million years ago—right at the dawn of complex life on the planet—the Earth’s oceans would’ve been significantly more green than they are today.

By Becky Ferreira If you were to look up from Earth some 466 million years ago, you might have seen a gleaming ring stretching across the sky, some scientists say. A study published this month ...

Earth may have had fresh, not just salty, water as soon as 600 million years after the planet ... existed by at least 3.2 billion years ago. Even if there was a freshwater cycle 4 billion years ...

Scientists theorize that without the protection of the magnetic field roughly 600 million years ago, solar radiation pounded the Earth’s atmosphere, stripping away hydrogen and other light gases ...
