A recently discovered group of nearby asteroids cold be an attractive location for extraterrestrial intelligence to land a probe to observe Earth, says a new paper. It may even have happened centuries ago.
Before we dismiss it as crazy talk, consider that Benford thinks that by ruling-out the presence of alien probes and extraterrestrial archeology on rocks that are often close to Earth would bring us to a profound conclusion: there is no-one out there and we’re truly alone.In this context, a co-orbital is an asteroid that goes around the Sun on the same, or similar, orbital path to Earth.
Illustation of American spacecraft Voyager 1which has survived space for twenty years and travelled over six billion miles. According to Benford, a lurker is a hidden, unknown and unnoticed observing probe, and they could have been sent to observe Earth long ago. “They may respond to an intentional signal and may not, depending on unknown alien motivations,” reads a news release covering Benford’s new paper. “Lurkers would likely be robotic, like our own Voyager and New Horizons probes.
Benford suggests that if we did find such a “lurker” we could simply photograph it and send it in a message simply to say “we see you” and wake the probe from its passive state.for allowing widely separated civilizations to communicate.At first glance, it’s way out there, but Benford thinks that the process of looking for relic alien spacecraft in Earth’s cosmic backyard is critical in us understanding the possibility of extra-terrestrial intelligence in our galaxy.
