Scientists have discovered that a 'weak spot' in Earth's magnetic field is growing at an alarming rate.
Known as the South Atlantic Anomaly (SAA), the region has expanded by an area nearly twice the size of Texas since 2014, and it is also slowly shifting westward toward Africa, according to a new study released on Monday.
The SAA has increased by up to 25 percent, as it moves about 14 miles west each year.
The expansion and movement are the result of turbulent flows of molten iron in Earth’s outer core, which generate unusual magnetic patterns that weaken the field in this part of the planet.
The Earth’s magnetic field, created by the swirling liquid iron thousands of miles beneath the surface, acts as a protective shield against dangerous charged particles from the sun and cosmic radiation.
Scientists warned that the weakening and shifting of this shield in the SAA is not just a scientific curiosity but has real-world consequences.
The SAA poses the greatest threat to satellites passing overhead, exposing spacecraft to higher levels of radiation that can temporarily disable electronics, corrupt data, or even cause permanent damage to critical hardware.
Satellites providing GPS, communications, and weather forecasting services for the US and around the world are particularly vulnerable when they pass through the anomaly.
Lead author Chris Finlay, Professor of Geomagnetism at the Technical University of Denmark, said in a statement: 'It's changing differently towards Africa than it is near South America.
'There's something special happening in this region that is causing the field to weaken in a more intense way.'
While regions outside of Earth contribute to the observed magnetic field, the primary source stems from inside the planet.

We’re all gonna die!...................again.............PING!...................
Anything in the Atlantic is already west of Africa.
The South Atlantic Anomaly has been there since the earliest days of satellites.
It changed reliable attenuation of incoming charged particles and satellites passing through would have their memory damaged.
This has not changed. Still happens. But if that situation is growing, satellite lifetime is going to shrink
There’s a magnetic pole flip that is due any century now. It should cause a lot of extinctions, mutations, and general havoc. It’s been said that the magnetic field is only about half what it was in ancient Roman times. The sun flips its magnetic poles every 11 years, but earth’s cycle is more chaotic and takes thousands.
Picky, picky...............
There will be a lot of confused geese...............
It’s Trump’s fault! Trump and those damned gasoline burning SUVs.
Womyn and minorities hardest hit.
The earth is getting flatter. Or fatter?
Signs and wonders are increasing.
Does this means more radiation penetrates into that region? If so, then it will be interesting to study cancer rates, etc. for those living there.
Would it have any effect on 31/Atlas’ course? Serious question from someone who knows absolutely nothing about this sort of thing. Would this growing anomaly affect comets, meteorites, satellites? Do rocket people have to figure in an offset?
I knew we should have parked the Earth farther away from the other, trashy-looking planets.
Nope, 31/Atlas will not get anywhere near Earth to be affected by it............
Nice weight loss plan.
Obviously SUVs are to blame.
Penguins, seals and seagulls...............
Unless, of course, we vote Democrat. Then everything will be sunshine and roses.
