Are we alone in the universe? Its a question that has plagued us since the ancient Greeks posed it for the first time in the 5th century and since then we have tried all manner of ways to reach out to our alien cousins.if they exist. We have fixed golden plaques to space probes, beamed messages out from radio telescopes and in 2012 even sent 10,000 X (formerly twitter) messages out to three star systems with the hashtag #ChasingUFOs! A new tool has been developed, rather mundane compared to these other examples, which is no bigger than a soft drink can and could detect signs of life on alien worlds with unprecedented precision.
