The Earth’s magnetic field surrounds our planet like an invisible force field – protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is continuously changing. Indeed, our planet’s…
A group of experts utilized the data collected by the ESA's SWARM satellites to show how the magnetic field is pulsating, where it's weakening and strengthening, and how fast these changes occur. For the first time, experts have mapped both the changes…
Research results of the new study indicate the rapid reversals of Earth's magnetic field which occurred about 550 million years ago is responsible for destroying a huge portion of the ozone layer. This destruction has, in turn, allowed a higher concentration of…
A group of researchers have studied ancient volcanic rocks to conclude that Earth's magnetic field is a long time away from "flipping" even if the magnetic field's intensity is reducing fairly fast. This is because Earth's current magnetic…
Scientists working in the desert badlands of northwestern Kenya have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered. The tools, whose makers may or may not have been some
It is known that Earth’s magnetic field has flipped many times throughout the planet’s history. Its dipole magnetic field remains about the same intensity for thousands to millions of years, but for incompletely known reasons it occasionally weakens (such is
