Gravity Assist: If They Call, Will We Listen? The Search for Technosignatures

So far we’ve talked about life in terms of its chemistry and telltale signs of biology. But what if there’s intelligent life out there in the universe that has created technologies just as good, or even more advanced, than our own? Some scientists are thinking about how we would detect the signals that would come from distant civilizations, if they are out there. Those signals are called “technosignatures.” Jason Wright, professor of astronomy and astrophysics at Penn State, has been thinking about the different technosignatures we could pick up using the telescopes we already have, and the telescopes that we could develop in the future.
