The Earth's magnetic field has been getting weaker over the past few centuries. This weakening can be seen in data gathered ...

A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, continues to attract focused attention from NASA researchers. This region, known as ...

During the Ediacaran period, approximately between 630 and 540 million years ago, Earth has remained a persistent and ...

NASA's MMS (Magnetospheric Multiscale) mission, consisting of four identical satellites flying in formation, constantly ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

Two enormous, supercontinent-sized 'islands' buried deep within the mantle have been revealed to have fundamental differences—contrary to previous assumptions—and they may even lead to Earth's ...

The solar wind flows around Earth's magnetic field. A new NASA study suggests that the amount of oxygen in the atmosphere and strength of the magnetic field have been correlated for more than half a ...

About 41,000 years ago, Earth’s magnetic field briefly flipped in what is known as the Laschamp event. Now, a group of scientists using data from the European Space Agency’s (ESA) Swarm mission have ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

External sources, such as the early solar wind or Earth’s magnetic field, were too weak or faded too early. Internal sources like a magma ocean or mantle-core precession might have helped, but ...

Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.
