Episode Title: Seeing a Black Hole with a Planet-Sized Telescope | STELLAR Produced by: It's Okay To Be Smart Description: Thank you to Draper and its Hack the Moon initiative for supporting PBS Digital Studios | Learn more at https://wehackthemoon.com It took about a century for black holes to go from impossible, to theoretical, to real. And it was just this year, in 2019, when we finally saw the first picture of a black hole! But how to you take a photo of something so massively dense that not even light can escape its gravitational pull? You use a telescope the size of the Earth! 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. Next up is Matt...

Episode Title: See INSIDE a Chrysalis! - Painting Wings with CRISPR Produced by: It's Okay To Be Smart Description: To learn more about The Great Courses Plus visit http://ow.ly/Mq4F30oTjJp SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ Butterfly metamorphosis is still a bit of a mystery. What happens inside a chrysalis to turn a caterpillar into a beautifully painted butterfly? Does it really turn to soup? I visited Dr. Arnaud Martin, who uses the CRISPR genetic modification technology to learn about how genes build bodies. Dr. Martin uses CRISPR to disrupt certain genes, and then looks for changes in butterfly wing patterns, creating designs we never see in nature. This tells us which genes control which part of the "wing painting" process. In the process of visiting Dr. Martin’s lab, I had my mind blown about what REALLY happens during butterfly metamorphosis. You will too. #butterflies #CRISPR #genetics Special ...

Episode Title: Where Your Eye Color Comes From… SurprEYESing Science! Produced by: It's Okay To Be Smart Description: Check out Say It Loud from PBSDS ►► https://www.youtube.com/SayItLoudPBS SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ The eyes are often the first thing we see when we look at someone. And when you look at them up close, everyone’s eye color is a kaleidoscope of shapes and hues. How does eye color work? The answer involves some very cool physics, and probably isn’t what you were taught in school. And you’ve probably wondered how is eye color inherited, or why some people have blue eyes even if their parents’ eyes are brown? Get ready for a long look deep into the genetics and physics of eye color. #eyes #eyecolor #blueeyes REFERENCES: Genetics of human iris colour and patterns - Richard A.

Hint: Look up 🙄 Watch our full episode about the science behind the monarch migration: URL Follow us to Atlas Obscura to learn about the discovery of this place: https://youtu.be/mXc1ZeRlOe0 Tens of millions of monarch butterflies fly to central Mexico’s mountain forests each winter from all over North America. It’s one of nature’s most incredible migrations. I was lucky enough to visit their winter home this year, and thanks to this VR180 experience, I get to share it with you. Listen closely, that sound you hear is millions of butterfly wings! #vr180 #monarchbutterfly #nature Filmed on location at La Reserva de Biosfera de la Mariposa Monarca - Michoacán, Mexico ----------- FOLLOW US for more curiosity: Twitter http://www.twitter.com/DrJoeHanson http://www.twitter.com/okaytobesmart Instagr...

Follow me to Atlas Obscura to learn about the discovery of this place: https://youtu.be/mXc1ZeRlOe0 Grab a headset and experience the monarch forest in VR180: https://youtu.be/fSa605IfTiE ↓↓↓ More info and sources below ↓↓↓ The monarch butterfly migration is one of nature’s greatest events. This orange-winged wonder travels up to 4,500 km from all over North America to spend the winter hanging from oyamel fir trees in central Mexico’s mountain forests. I got to go there. Seeing tens of millions of butterflies dangling from the treetops is a truly breathtaking sight. But how does an animal with a brain the size of a poppy seed navigate to this one special place, especially since the last monarchs to make the trip lived 4 or 5 generations earlier? Get ready for an amazing story of science, instinct, and navigation. #nature #monarchbutterfly #migration Special thanks to: Atlas Obscura: @atlasobscura Jason Goldman: @jgold85 Phil Torres: @phil_torres Filmed on location at: La Reserva de B...

I bet you never even notice that it’s there. Yet you are swimming in an ocean of it every day. If there’s a literal ton of air pressing down on you all the time, so why don’t we feel it? We look back at the history of physics to learn how we figured out air pressure, why vacuums don’t suck, and how people like Galileo, Torricelli, and Otto von Guericke changed science forever with a few simple experiments. #AirPressure #Physics #Atmosphere DISCLAIMER: Do not perform the trash bag experiment without adult supervision.
