Scientists are turning Earth itself into a cosmic detector to hunt for the tiniest, most elusive dark matter particles—ultralight axions and dark photons—using our planet’s magnetic field and atmosphere as a giant natural resonator. This breakthrough method bypasses lab-size limitations, allowing researchers to probe previously inaccessible frequencies. By analyzing a decade of geomagnetic data from a Scottish observatory, they filtered out noise to spot potential signals: tighter constraints on axion-light interactions, plus mysterious unexplained candidates for dark photons. It’s a bold new…
