CAMBRIDGE (CBS) — Firing a megawatt laser into space with the goal of attracting alien attention is technologically feasible, according to a new MIT study.

The research published recently in The Astrophysical Journal says the laser beacon could be “something of a planetary porch light” and find its way to possible life forms as far as 20,000 light years away.
