Planet Nine 

Since Pluto was downgraded to a dwarf planet, this object on the outskirts of our Solar System has continued to fascinate astronomers. The New Horizons probe flyby in 2015 revealed a world far more complex than anyone had expected and offered a new perspective on other objects near Pluto, in the Kuiper belt.

The study of these objects with such magical names - Eris, Sedna, Haumea and many more – suggests that there may be a new planet hidden beyond the Kuiper belt. Follow Mike Brown and his team of three fellow Californian astronomers as they search for this ninth planet!

The Secrets of Gravity

Two friends on a trip through space and time.

Why do things magically fall to the ground rather than floating in the air? This is the very question that the young apprentice magician Limbradur asks. He wants to find out all he can about this law of nature and the mysteries of the universe. So, one night, he uses his magic powers to sneak into the Albert Einstein Museum. There, he encounters ALBYX3, a small, clever but rather quirky robot who knows all about Albert Einstein and his theories. Alby takes Limbradur on an exciting journey through space and time, during which he explains the principles underlying gravitation, but also learn much about friendship and imagination.


The double feature is preceded by a presentation on tonight’s sky.
