In the celebrations of the total solar eclipse of 1919, take part in astronomical observations, guided visits to a historical observatory, and a public talk dedicated to the dark side of the Universe.
The 29th of May marked the centenary of the observations of the total solar eclipse of 1919, in Sobral (Brazil) and Príncipe (São Tomé e Príncipe), which resulted in the confirmation of one of Einstein’s General Relativity Theory predictions.
The discovery of unexpected components of the Universe – dark matter and dark energy – makes us reconsider Einstein’s gravitation theory, which, in all other aspects, has been summing up sucess after success. The dark side of the Universe is the theme of the talk of Tiago Barreiro from Instituto de Astrofísica e Ciências do Espaço (IA) and Universidade Lusófona.
All activities are free, but the talk is limited to the number of places available. The guided visits to the observatory require prior registration upon arrival.
