Science Centre AHHAA is the biggest science centre in Estonia and the Baltic states, located in Tartu. The main purpose of AHHAA is promoting science, technology and the scientific approach to solve common disadvantages.

Since 7 May 2011, Science Centre AHHAA has been located in a building in the centre of Tartu.


AHHAA was established as a project of the University of Tartu on 1 September 1997 and by 2004 it had developed into a foundation constituted by the city of Tartu and the University of Tartu.[1] From the very beginning, the head of Science Centre AHHAA was Tiiu Sild. In 2008, the AHHAA 4D Adventure Cinema was opened in the Lõunakeskus shopping centre in Tartu. In 2009, a branch office of Science Centre AHHAA was opened in Tallinn at the Freedom Square (the Tallinn branch was closed at the end of 2013). On 7 May 2011 Science Centre AHHAA in Tartu opened the doors of its new, 11,156 m² building engineered by architects Vilen Künnapu and Ain Padrik in the heart of the city.

The activities of the Science Centre AHHAA Foundation are coordinated by a committee composed of Hannes Astok, Anneli Saro, Jaanus Karv, Mart Laidmets, Reno Laidre and Vallo Mulk.

Additionally, the practical aspects of the activities of the foundation are appraised by a science committee composed of experts.


Science Centre AHHAA offers a view of the starry skies in a fully spherical hybrid planetarium (which means that there is a possibility to show the skies with both optical and digital projection, which can be displayed either separately or together).

Constructional and technical side[edit]

The uniqueness of AHHAA's planetarium lies in the fact that in addition to the ordinary view on the ceiling and the walls, the image of the skies in the planetarium of the centre also extends under the floor, which is the reason why the floor of the planetarium is made of glass.[2]


  • 9 meters in diameter
  • 20+5 seats
  • The first planetarium in Europe to use the MEGASTAR projector
  • Currently the first and the only hybrid-planetarium (multiple projector system) in the Baltic states

The AHHAA Planetarium belongs to two organisations:

  • The Nordic Planetarium Association
  • The International Planetarium Society

4D Adventure Cinema[edit]

Science Centre AHHAA had a 4D Adventure Cinema, located in the Lõunakeskus shopping centre on the southern edge of Tartu. The cinema was open from 18.07.2008 to 31.12.2017[3]



The Science Centre AHHAA Foundation regularly organizes special events. Some of the most reputable events are listed below:

  • The annual Researchers' Night Festival – organized all over Estonia in the end of September and consisting of different events promoting a scientific approach to matters (such as Science Cafés, science theatre shows, tours in laboratories, workshops etc.).[4]

International representation[edit]

The Science Centre AHHAA Foundation participates in science festivals and fairs both in Estonia and abroad, its main “trade tricks” being the science theatre shows and various workshops. During the past few years Festival della Scienza and Perugia Science Fest[5] in Italy, Korea Science Festival[6] in South Korea, Moscow Science Festival[7] in Russia, Science Picnic in Poland and Science Festival Belgrade[8] in Serbia have been among the few places where Science Centre AHHAA has been represented.
