Researchers say attracting aliens to Earth could be as easy as leaving a very large “porch light” on.
MIT released an image, along with a study from researchers.
The study says the light from a laser could spark interest from extraterrestrials, if they exist.
The powerful laser would be focused through a telescope aimed toward space.
The author of the study says the necessary lasers have already been invented, but they still need a large enough telescope.
