The Instituto de Astrofísica e Ciências do Espaço (IA) is a research infrastructure with a national dimension.
It embodies a bold vision for the development of Astronomy, Astrophysics and Space Sciences
in Portugal, taking full advantage and fully realizing the potential created by the national membership of the
European Space Agency (ESA) and the European Southern Observatory (ESO).
IA resulted from the merging, in 2015, of the two most prominent research units in the field in Portugal: the Centro de Astrofísica da Universidade do Porto (CAUP) and the Centro de Astrofísica e Astronomia da Universidade de Lisboa (CAAUL).
Currently IA is the biggest research unit of this area in Portugal, hosting more than two-thirds of all active researchers working in Space Sciences in Portugal. It is also responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
