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 bright 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. 

Hundred years after, our vision of the Universe is extraordinarily more vaste than in Einstein’s time. In the meanwhile, the American astronomer Edwin Hubble showed that our galaxy is only one in a cosmic ocean inhabited by other galaxies.

What do we know today about these islands of light that spread in vast groups through space, as far as astronomical instruments can reach? How did galaxies form and what is their common story? We will close the cycle “100 years of space-time” with a voyage to this bright side of the Universe.

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.

Organized by IA, this event is part of the exhibition E3 – Einstein, Eddington and the Eclipse, framed within the project Eddington @ Sundy: 100 years after.
