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.

The dent wasn’t there when the Earth drove the magnetic field on its date with the moon, I swear Dad!!
That’ll buff right out!
Marty McFly: “Whoa. This is heavy.”
Doc Brown: “There’s that word again. ‘Heavy.’ Why are things so heavy in the future? Is there a problem with the Earth’s gravitational pull?”
Okay then, I’ll cancel my hair appointment.

Movie screenshot.
Woman: I’m okay with it so long as my makeup will still look perfect after the crisis is over.
Example: One Million Years BC where Raquel Welch needed no visits to her stylist or makeup assistant after deadly battles with dinosaurs and survival against he elements.
Who is that semen demon?
Ha.
As the space aliens said to the US after the short lived Moon exploration program:
You earthlings are grounded. Space shuttle distance only. No farther.
Note: This is a theory of some people about why the program ended.
I keep dying but I’m not still dead.
Yeah, Raquel always looked primal.
I was trying to find a screen shot of the moment the young male scientist figures out the secret that will save the world, with his comely lab assistant looking at him in puzzled admiration. That was the closest I could find.
Trump’s fault.
Trump’s fault.
That rumbling sound is Newton turning over in his grave.
That’s a good movie It Came from Outer Space (1953)
Liberal scientists will figure out that it is President Donald J Trump’s fault and demand they need a grant to study it and a tax to make sure it won’t grow...
It’s a start! I feel the magnetic hole is shrinking already.
I’ll second that......
No worries, that thing has been going on for millions of years. And Earth is still here.
What sort of sorcery is this? An apple? Whence came this to be? And how?
