EXCERPTS: It has produced one of the most consistent sets of negative results in the history of science. For more than 60 years, researchers have tried to find a single convincing piece of evidence to support the idea that we share the universe with other intelligent beings. Despite these decades of effort, they have failed to make contact of any kind.
But the hunt for alien civilisations may be entering a new era, researchers believe...
[...] “Until now, we have been restricted to looking for signals deliberately sent out by aliens to advertise their existence. The new techniques are going to be so sensitive that, for the first time, we will be able to detect unintentional transmissions as opposed to deliberate ones and will be able to spot alien airport radar, or powerful TV transmitters – things like that.”
The importance of being able to detect civilisations from the signatures of their everyday activities is supported by astrophysicist Prof Adam Frank of the University of Rochester in New York. “By searching for signatures of an alien society’s day-to-day activities – a technosignature – we are building entirely new toolkits to find intelligent, civilisation-building life,” he writes in his new book, The Little Book of Aliens.
All sorts of technosignatures have been suggested as indicators of the presence of alien civilisations, from artificial lighting to atmospheric pollution... (MORE - missing details)
