CAMBRIDGE, Mass. — Attracting aliens might be as easy as leaving a really, really big light on.

A new study from MIT suggests that the light from a laser could spark the interest from aliens if they exist.

The powerful laser would be focused through a telescope aimed toward space.

The study's author, James Clark, says while that is difficult it's not impossible. He says the lasers have already been invented, they just need a telescope that is big enough.
