Wrong frequency? Astronomers rethink where to hunt for alien signals
Humanity’s search for alien life has long been fixated on a single,
cozy corner of the radio spectrum.

Quote:
Astronomers might be hunting for alien signals in all the wrong places.
A new study by PhD researcher Louisa Mason (University of Manchester)
suggests astronomers may be missing potential extraterrestrial signals
by focusing too narrowly on radio frequencies.
We assumed extraterrestrials would act like us. Hence, the search for
alien intelligence was mostly concentrated on a narrow band of the
radio spectrum known as the “water hole.“
What if the rest of the galaxy left that frequency behind long ago,
leaving us listening to dead air while a bustling galactic
conversation hums away on higher bands?
That question is driving a quiet revolution in the Search for
Extraterrestrial Intelligence (SETI).
