Earth’s powerful magnetic field shields life on the planet from the severe cosmic radiation as we know it. This is what sets our blue world apart from Venus and Mars. However, the Earth’s ...
Just over 2 billion years ago, smack-bang in the middle of the Paleoproterozoic period, Earth's magnetic field was strong. Roughly 1.5 billion years later it dropped to its lowest ebb – about 30 ...
A new study suggests more solar radiation reached Earth while the magnetic field weakened, leading to a rise in oxygen that drove an explosion of multicellular organisms during the Ediacaran ...
The planet's magnetic field may have collapsed around 600 million years ago, enabling a major oxygenation event and perhaps supercharging evolution. A near collapse of Earth's magnetic field may ...
Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Sally Sara: New research is examining the theory that changes in the Earth's magnetic field could ...
The emergence and diversification of multicellular organisms on Earth appears to have coincided with the weakest magnetic field in Earth's history, which suggests a direct correlation. This has ...

Earth’s magnetic field plays a key role in making our planet habitable. The protective bubble over the atmosphere shields the planet from solar radiation, winds, cosmic rays and wild swings in ...
A £13 million Wiltshire mansion where Nancy Mitford and Siegfried Sassoon once partied with 'the brightest of the Bright Young Things' After Wilford Manor's glory days in the 1920s it became a ...
A 76-year-old man who collapsed while on a walk near Stamford has thanked the off-duty police office who saved his life. Brian Kinealy nearly died after becoming unwell during a Sunday morning ...
A near collapse of Earth's magnetic field may have paved the way for life to evolve past the microscopic stage. New research on ancient rocks from South Africa and Brazil suggests that Earth's ...
