Even during rain or in the daytime, in a planetarium, we can enjoy a sky, full of
stars.
But, this wonderful invention did not simply appear out of nowhere.
Throughout history, humanity has been fascinated by the night sky, and various
mechanical models were built, ultimately leading to a magical innovation, to
dynamically represent the starry sky.
In ancient Greece, celestial globes, orreries, and astrolabes were created for
simulating the motion of stars and planets. How have these models contributed to
the development of the planetariums of today?
In this program, you can travel back in time to 100 years ago. Following the notes
of the original inventors, you can re-live the challenges and triumphs behind the
birth of the modern planetarium.
