The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of the European continent over the past 11 years. Using data from the European Space Agency’s (ESA) Swarm satellites, scientists revealed that the South Atlantic Anomaly has …

A weak region in Earth’s magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. That’s according to data collected by the European Space Agency’s (ESA) Swarm satellite constellation over the last 11 years. Swarm has been monitoring a region known as the South Atlantic Anomaly since 2014, and scientists have …

A weak spot in Earth’s magnetic field over the South Atlantic Ocean has ballooned in size since 2014, satellite data reveals. The region, known as the South Atlantic Anomaly, has grown by an area nearly half the size of continental Europe, sprouting a lobe in the direction of Africa where the field is weakening the fastest. And the anomaly, linked …

A weak spot in the Earth’s magnetic field is growing over the South Atlantic Ocean, according to more than a decade’s worth of satellite data collected by scientists.  The magnetic field surrounding Earth protects the planet from cosmic radiation and particles charged by the sun. Scientists believe it is generated by the outer core of the Earth, according to a …

A giant dent in Earth’s magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world. It’s called the South Atlantic Anomaly, stretching across the gulf that separates Africa from South America, and the latest data suggests that it has expanded by roughly half the size of continental Europe since 2014, while …

Applications 13/10/2025 5053 views 25 likes Using 11 years of magnetic field measurements from the European Space Agency’s Swarm satellite constellation, scientists have discovered that the weak region in Earth’s magnetic field over the South Atlantic – known as the South Atlantic Anomaly – has expanded by an area nearly half the size of continental Europe since 2014. Earth’s magnetic …

IN A NUTSHELL 🛰️ NASA monitors the South Atlantic Anomaly, a region impacting satellite operations due to weakened magnetic intensity. 🌌 The anomaly poses risks to spacecraft systems by exposing them to charged solar particles. 🔍 Research reveals the SAA’s dynamic evolution, including a potential split into two distinct cells. 🧭 The anomaly’s broader implications affect Earth’s magnetic field and …

“It Was Hiding All Along”: Scientists Discover Carbon May Have Triggered Earth’s Core to Crystallize (and saved our magnetic field)  Rude Baguette Source link

A view of the Earth’s interior around 1 billion years ago: Tangled magnetic field lines inside the core are linked with the Earth’s exterior magnetic field. (Scientifically correct image from a research simulation). Credit: ETH Zurich / SUS Tech A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into …

Under the right conditions, superconducting magnets allow electricity to flow essentially undisturbed, producing intense magnetic fields for a variety of uses, including nuclear fusion experiments. Naturally, a larger magnetic field gives scientists more room to explore—something that may soon be available to physicists in China, thanks to the creation of a record-setting superconducting magnet. In a September 28 statement, the …
