NASA's mission is to pioneer the future in space exploration, scientific discovery and aeronautics research. To do that, we have worked around the world -- and off it -- for more than 50 years, searching for answers to fundamental questions about our place in the universe. We're exploring space and discovering Earth. Join us for this exciting and important journey.

On this channel I make various space and science related videos, and also comparisons of things in our Universe.

Animation videos explaining things with optimistic nihilism since 12,013. We’re a team of illustrators, animators, number crunchers and one dog who aim to spark curiosity about science and the world we live in. To us nothing is boring if you tell a good story. For updates on our videos and other news from the kurzgesagt universe follow us on Twitter, Facebook, Instagram and LinkedIn.

SciShow Space explores the universe a few minutes at a time. We share everything from just after the beginning of time to new innovations in space exploration. For the most recent space science, check out our new videos on @SciShow. And for young thinkers, visit SciShow Kids!

Scott Manley is someone who fell into youtube because he felt a deep compelling need to teach people orbital mechanics and rocket science so they could play Kerbal Space Program, now, years later the gaming videos are less important and the pure science is the main thrust. My degrees are all in Physics and Astronomy, so much of the rocket science and engineering I've learned is self taught, always learning, always teaching. I'm not a professional youtuber, I have a day job in software development which means I won't take lame sponsored content, or tell you to sign up for affiliate services to make a quick buck. However lots of generous people have asked to support my hobby via Patreon and I'm grateful to those individuals. Also occasionally shares cute videos of his kids. And for everyone asking about the music at the end of my videos http://ccmixter.org/files/tigoolio/45377

Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth with our astrophysicist host: Matthew O’Dowd. Check for New Episodes on Wednesday afternoons! Matt O'Dowd spends his time studying the universe, especially really far-away things like quasars, super-massive black holes, and evolving galaxies. He uses telescopes in space to do it. Matt completed his Ph.D. at NASA's Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. He's now a professor at the City University of New York's Lehman College and an Associate at the American Museum of Natural History's Hayden Planetarium. Previous host Gabe Perez-Giz is an astrophysicist who studies black hole physics. He received his Ph.D. from Columbia University and also hosted PBS Infinite Series.
