The International Olympiad on Astronomy and Astrophysics (IOAA) is an annual event in which high school students from around the world solve theoretical, analytical and observational problems in the fields of astronomy and astrophysics.

The 6th IOAA will be held in the State of Rio de Janeiro, in the beginning of August, 2012. 

We expect to welcome participants from all over the world, specially new teams from Latin America, due to the proximity to Brazil.
