The Ways Aliens Might Find Us

Humans may not yet have encountered life outside of our planet, but many scientists see it as an inevitability. In 1960, astronomer Frank Drake came up with the now eponymous equation which provided an estimate of the number of civilizations in our galaxy.

Although scientists continue to debate the application of his formula as well as alternatives, Drake’s own solution to the equation is 10,000 civilizations, suggesting intelligent, technologically advanced life outside our planet is common.

How these different civilizations, including our own, find each other is an important question for anyone here on Earth looking for extraterrestrials. Here’s a look at how aliens might stumble upon our planet — and how we might actually spot them first.
