One of the fundamental questions humanity has always asked is how big is our Universe? For much of human history, people believed that Planet Earth was the very center of the entire universe. And Earth is pretty big. But compared the rest of the universe, we are infinitesimally small.

The animation in this video the Digital Universe data collection curated by the American Museum of Natural History. The software is used to visualize these datasets is OpenSpace, which is developed through a collaboration between AMNH, Linköping University in Sweden, New York University, and the University of Utah. The software and datasets are open source and are free to download and explore.

I know, this video is a bit different from most Space Time videos. It’s part of a PBS miniseries called Stellar, done in collaboration with Diana Cowern from @physicsgirl and Joe Hanson from @It’sOkayToBeSmart. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists. Next up is Joe’s episode where he explores where life might be outside our solar system.

Check out Joe’s episode here:
