This is why, this year, we’re sending a signal to a neighbouring Alien Solar System (science video).
METI will send a signal to the Trappist-1 Solar System in October 2022, a system with potentially three Earthlike planets that is just 39 light-years distant.
But, considering how little proof of alien civilisations has been found, do we really want to start broadcasting? What harm may ET pose if they aren’t friendly?
What we don’t want to invite to visit Earth?
