• Earth could contact aliens using laser 'porch light', MIT study says


    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.
