Summary

The conference, presented by Johan Richard, focuses on the recent signing of the contract for the BlueMUSE instrument, a new 3D spectrograph for the VLT. Richard explains the basics of telescopes and spectroscopy, highlighting the success of the MUSE instrument. BlueMUSE will observe in the blue/UV part of the spectrum, complementing MUSE and other instruments. Its scientific goals include studying comets, massive stars, gas flows in galaxies, and the formation of galaxy clusters. The talk also covers the technical design, the collaborative effort, and the timeline for construction and installation. Richard briefly mentions other projects like HARMONI on the ELT and the future WST. The presentation includes an image mystery and a Q&A session.
