Physics Girl explores how We’ll Find the Aliens in Our Solar System!

Looking up at the stars makes you wonder: what and who is out there? And why haven’t we seen any other intelligent civilizations given the vast size and age of the universe? They’re complicated questions and although we haven’t met any other space-faring species we do have a way of calculating just how many alien civilizations might be out there as well as some rather frightening ideas as to why we might not have met them.

This video is a bit different from most It's Okay To Be Smart videos. It's part of a new PBS miniseries called STELLAR, done in collaboration with Matt O’Dowd from PBS Space Time and Dianna Cowern from Physics Girl. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists to bring you the most exciting stories about space.

**I figure out how we took a picture of a Black Hole with a telescope the size of Earth

**Matt O’Dowd exploring the oldest quasar ever seen at the Gemini Telescope:

**Physics Girl visits LIGO to learn about gravitational waves:

You'll be able to see future episodes on the Physics Girl, Space Time and It’s Okay to be Smart YouTube channels, as well as the PBS Digital Studios Facebook page.

Stellar is a part of the PBS Summer of Space. They'll be lots of awesome space related content all summer long on PBS. See what's happening at
