Science Centre AHHAA, Tartu, Estonia

"The aim of Science Centre AHHAA is to introduce science to everyone and encourage studying through the joy of discovery. By autumn 2013, more than 2 million people of different age have visited our exhibitions and other science events. In addition to trying out numerous "hands-on" exhibits on our various exhibitions, visitors of AHHAA can also take part in workshops, enjoy planetarium and science theatre shows. We also offer several special programmes for schools. AHHAA welcomes visitors of all ages and offers a great opportunity to spend a fun day filled with science!" [AHHAA English website]


One unique feature at AHHAA is its planetarium. "In addition to the ordinary view on the ceiling and the walls, the image of the skies in the planetarium of the center also extends under the floor, which is the reason why the floor of the planetarium is made of glass.

The AHHAA-type fully spherical planetariums are world-scale rarities as most planetariums around the World are dome-shaped half-spheres. The extraordinary nature of the full sphere can be best understood when experiencing the effect of being in the middle of the stars while sitting in the planetarium – the projection of the starry skies reaches from high above to the surrounding walls, stretching deep down under the stargazers' feet.

The Megastar-type projectors used in AHHAA are capable of projecting about 5 million stars and are thus the proud owners of a Guinness record for being the mothers of all planetariums." [Wikipedia]


This level of immersive experience comes at a cost - the planetarium is fairly small and holds a maximum of just 16 people for each show. A quick look at their website shows that the planetarium is usually fully booked. If you are in the city of Tartu and to avoid disappointment, best to book a seat by phone before visiting.
