The phenomenon known as gravitational lens has its origin in the bending of light by the gravitational pull. Since Eddington’s observations, celebrating now 100 years, many advances have occurred in the understanding and in the observation of gravitational lenses, which are today at the center of the space mission Euclid, the next large mission in cosmology supported by the European Space Agency.

This science café presents the phenomenon and discusses the several types of gravitational lenses that we know in the Universe. It will also describe some applications of gravitational lenses that have been contributing to the advance of our understanding of the Universe and in particular the ones used by the space mission Euclid.


Ismael Terenoa researcher at the Instituto de Astrofísica e Ciências do Espaço and teaches at the Faculty of Sciences of the University of Lisbon. He holds a PhD from the Institute of Astrophysics of Paris, where he worked with a team that made the first detection of gravitational lenses from cosmological effects. He is one of the researchers responsible space mission Euclid in Portugal.
