AHHAA is a foundation created by Tartu University, Tartu city and Estonian Ministry of Education and Science. The aim of Science Centre AHHAA is to introduce science to everyone and encourage studying through the joy of discovery. More than 3 million people of different ages 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! We value highly international cooperation and therefore we participate in projects.
