# La Science s'aMuse: From the infinitely large with Spirou to the infinitely small...

Welcome to the program co-produced by the University of Montpellier and Divergence-FM, which takes you on a cruise through the laboratories of the Muse archipelago. Today's cruise is a far-off one, as we welcome Julien Morin, a researcher at Montpellier's Laboratoire Univers et Particules, who talks to us about exoplanets. Then, in the second half of the program, we explore the infinitely small with a transmission electron microscope...

In the course of our journey, we've taken you to the depths of the sea, to Egyptian tombs, to the South to meet ecologically rare species and to the habitat of the future. Today, hold on tight to your seats as we take you...into space!

The Laboratoire Univers et Particules de Montpellier (LUPM), in collaboration with other French laboratories, has just measured for the very first time the mass and density of a very young exoplanet located in the Au Mic planetary system, named after its star Au Microscopii. This discovery was made possible by Spirou, the new high-precision spectropolarimeter/velocimeter recently installed at the Canada-France-Hawaii Telescope.
Julien Morin is our guest today, specializing in stellar and exoplanetary physics at LUPM.

In the second half of the program, we move from the infinitely large to the infinitely small, from the Microscope constellation to the electron and analytical microscopy platform, to discover a strange and imposing machine, the transmission electron microscope. Erwan Oliviero gives us the tour.
