Lights on the Invisible. A trip to Laniakea and more

Astrophysicist Helene Courtois takes us on a walk through the heart of the largest structures that the Universe has ever formed, during a giant arm-wrestling between two mysterious and invisible entities.
Cosmography is the science that maps and measures waves, cosmic voids and extragalactic super-continents.
Being a cosmographer is to probe the lights that reach our telescopes on Earth and in space. These lights allow us to understand the great movements of galaxies and invisible matter.
Helene will take us on a journey through the great watershed she discovered: Laniakea, home of our Milky Way. Its neighbouring continents were revealed a few months ago, at the same time that the largest international collaboration of astronomers was sending into space a legacy telescope for humanity: Euclid. We will experience the excitement that researchers are in, because as we map further, it is gravity and space expansion that will reveal their secrets.
