Everyone has their own opinion as to whether or not aliens exist. But let’s assume they do for a second and we wanted to let them know we're here!!!! How should we signal our species' existence through the expanse of space? There are a few options, but which is the most effective and the cheapest? Find out in this week’s episode of PBS Space Time!

Congrats to last week’s Balloon Challenge Winners!
