A strange anomaly weakens Earth's magnetic field between South America and Africa, puzzling scientists and raising concerns.
Satellites and spacecraft face increased exposure to solar particles in the anomaly, risking glitches and data loss.
NASA likens the South Atlantic Anomaly (SAA) to a "dent" in Earth's magnetic field, disrupting systems in orbit.
The swirling molten iron inside Earth's core, along with dense rock structures, is linked to the anomaly's emergence.
NASA researchers observed that the anomaly appears to be dividing into two distinct regions of weakened intensity.
A 2020 study suggests the anomaly may have persisted for 11 million years, not a recent or isolated occurrence.
Tracking reveals the anomaly slowly shifts over time, creating evolving challenges for spacecraft operators.
A recent study connects the SAA to changes in auroras, adding a visual dimension to its mysterious influence.
Continued observations and missions are essential to model and predict the anomaly's evolving behavior.
