Particles of the highest energies heading to Earth seem to be labeled with the addresses of nearby galaxies. Seven of the ten brightest neighbors coincide with hotspots in the sky—chance can't explain it. Their source might be neutron star collisions.
🎯 One such particle, smaller than an atom, carries energy comparable to a baseball's impact—like a carrier pigeon delivering a truck.
