    Is This Why We Haven’t Found Alien Civilizations? | STELLAR

    Thank you to Draper and its Hack the Moon initiative for supporting PBS Digital Studios | Learn more at https://wehackthemoon.com Physics Girl explores how We’ll Find the Aliens in Our Solar System! https://www.youtube.com/watch?v=zfqpYDVhXd8&t=1s Uploaded 22-07-19 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 https://www.youtube.com/watch?v=gUpKta9yfCk&t=237s **Matt O’Dowd exploring the oldest quasar ever seen at the Gemini Telescope: https://www.youtube.com/watch?v=cqCPnXHKO5c **Physics Girl visits LIGO to learn about gravitational waves: https://www.youtube.com/watch?v=jtp71NT0GNg 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.

    Why Solar Eclipses Are Such a Huge Deal

    Join our Patreon community: https://www.patreon.com/itsokaytobesmart SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ On April 8, 2024, the Moon’s shadow fell upon the Earth, creating a total solar eclipse across North America. If you had the chance to see it, you're surely glad you didn't miss it. It’s an amazing coincidence that total eclipses happen at all — and that we’re alive at a time when we can see and predict them. We made this video so you can learn how to watch an eclipse safely, what to look for during an eclipse, why eclipses happen, and how eclipses have helped advance scientific research.

Sea otters are a keystone species, meaning that an entire ecosystem depends on their presence. After they were nearly hunted to extinction for their dense fur, sea urchins (the otters' favorite food) nearly destroyed the Pacific kelp forests, a habitat that hundreds of species rely on for food and shelter. Thanks to the hard work of conservation scientists at places like the Monterey Bay Aquarium, sea otter populations are on their way back.

This is the story of a WWII wartime codebreaker and his quest to decode nature’s most beautiful patterns.
