Colorado. Nikola Tesla, while working at night, occasionally received regular radio pulses, and speculated that they might be radio signals from Mars, suggesting he was the first to receive greetings from another planet. In hindsight, one explanation might be that he picked up radio signals emitted by Guglielmo Marconi’s team, but Marconi transmitted in RF waves, while Tesla listened in VLF (8-22 kHz), and Marconi’s equipment didn’t (yet) have enough power to transmit across the Atlantic. According to brothers Kenneth and James Corum, Tesla may instead have picked up radio signals from Jupiter’s moon Io as it passed through the torus of charged particles surrounding the gas giant. These radio pulses are precisely 10 kHz and were discovered in 1955. To test their theory, the Corum brothers reconstructed Tesla’s equipment, and in 1996, they detected electromagnetic pulses similar to those described by Tesla.
