How is it that astronomers still don't know what makes up the majority of the universe? Dark matter composes far more of the universe than the "ordinary" matter like stars, planets, and dust-- but scientists are still working to understand what it actually is. The Dark Matter Mystery, produced by the Laupheim Planetarium in Germany, is an in-depth, immersive exploration of this contemporary frontier in astronomy. Learn more about the properties of dark matter and the techniques being used to attempt to detect it. Look back at the discovery of the planet Uranus and even further to the evolution of the early universe to understand how the contours of the unknown continue to shape the development of our science. It is time to be curious. The Dark Matter Mystery is suitable for all ages but geared for high school and adult audiences, with a running time of approximately 30 minutes.
