The Best Of Our Knowledge #1159

During the presidential election season there was a lot of talk about illegal aliens.  Well, get ready...we’re about to talk about aliens again...but the other kind, the ones from outer space. Today on The Best Of Our Knowledge, our astro-biology series returns with a look at the search for extraterrestrial life, and what finding it might mean for our society.

Then we’ll spend an Academic Minute taking a look at a very different kind of aliens species...one that is already having consequences here on Earth.
