Researchers at the Massachusetts Institute of Technology suggest laser technology could act like a porch light for Earth to attract aliens — if they exist.

A study published in The Astrophysical Journal said creating a 1- to 2-megawatt laser focused through a telescope aimed toward space could produce a light strong enough to stand out from the energy produced by the sun.

James Clark, graduate student in MIT’s Department of Aeronautics and Astronautics and author of the study, acknowledged creating this project would be “challenging” but not impossible.

“If we were to successfully close a handshake and start to communicate, we could flash a message, at a data rate of about a few hundred bits per second, which would get there in just a few years,” Clark said in a statement.
