Invisible electric waves in Earth's magnetic field act like cosmic vacuum cleaners, scrubbing away 'killer electrons' that threaten satellites and astronauts. New research reveals how this natural defense system works.

KEY TAKEAWAY Earth's radiation belts contain electrons moving at 99% light speed—enough energy to penetrate 1mm of lead

KEY TAKEAWAY NASA's Van Allen Probes detected chorus waves (electromagnetic pulses) scattering 90% of dangerous electrons

KEY TAKEAWAY The findings will improve radiation forecasting for satellite operators and space agencies

KEY TAKEAWAY This natural process may inspire new ways to shield spacecraft from cosmic rays

KEY FACT A single killer electron carries enough energy to flip 100,000 computer memory bits—equivalent to corrupting 12 KB of data.
