It's been the basis of pretty much any Hollywood blockbuster associated with humans making contact with an extraterrestrial species. There's many questions to be asked, so let's get started. Without question this is one of the most famed and fabled events in the relatively recent history of astronomy. So why do they persist? It all comes down to the WOW signal. ![]() There's a great deal to dampen the expectations of even the most ardent sky-watcher. Plus factor in the immense distance between potential life hosting planets - we're talking light years here - and guess that any signals sent using this technology would have been likely hundreds of years old. So is it likely that such a signal may somehow appear? After all it assumes that our alien cousins have independently devised radio signals which are readable on our own devices. However in the modern context the search has become incredibly more advanced.Įven though the majority of scientists prefer to use heat and oxygen sensitive measures nowadays when looking for ET, there's still a solid number who still vouch for the classic radiography approach. ![]() The famed Nikola Tesla is arguably the pioneer, using his groundbreaking wireless technology to search for life on Mars way back in 1896. SETI (Search for Extraterrestrial Intelligence) has in one way or another been around since before the days of practical human flight. ![]()
