ResumoKRAUS1 has recently reported the reception of impulsive radio signals at a wave-length of 11 metres and concludes that these originate in the planet Venus. On three occasions, a pulse was followed by a weaker one which sounded like an echo. Kraus suggests that these ‘echo’ signals travelled from Venus to the Earth via the Moon, since the observed time differences of about one second between the primary and secondary pulses were within 10 per cent of the calculated delay times between a direct signal and one reflected from the Moon. This echo phenomenon is then used for making more definite the identification of the radiation as Venusian in origin.
