Humans dream of finding life on Mars — but could our fascination with this neighbouring planet broadcast our existence to aliens who live much further away?
A review of the most powerful signals that humans have sent into space has shed light on how extraterrestrials might find us.
The study analysed the logs of Nasa’s Deep Space Network (DSN), an array of radio dishes in California, Spain and Australia that communicate with the agency’s far-flung spacecraft. It concluded that the bulk of humanity’s most powerful, persistent signals into the cosmos had been directed not at distant stars but at machines orbiting or roving the red planet.
If you have the time check out “The Program” from James Fox. It’s only available to watch (free) on Youtube but well worth a look with a lot of interesting info.
Meanwhile Jacques Vallee is an interesting researcher of long standing.
