Célébrations de la pose du dôme de l’Extremely Large Telescope de l’ESO
16 avril 2025
L'Extremely Large Telescope (ELT) de l’ESO a récemment franchi une étape symbolique importante : avec la structure de l’un des panneaux coulissants de la coupole désormais entièrement installée — et une grande partie de l’autre également en place — la construction de la coupole de l’ELT a atteint son point le plus haut. L’événement a été célébré aujourd’hui à Garching, en Allemagne, où l’ESO a organisé une cérémonie à son siège en présence de partenaires industriels et institutionnels, ainsi qu’au sommet du Cerro Armazones, au Chili, sur le site de construction, à l’occasion de ce que l’on appelle la cérémonie de "Topping Out" — ou cérémonie du faîtage.
Lors de cette cérémonie, également connue sous le nom de Tijerales au Chili, les drapeaux de l'ESO et du Chili ont été hissés au sommet du dôme du télescope, et un barbecue traditionnel a été organisé pour les personnes qui ont travaillé dur sur le site de construction. Le gouverneur Ricardo Díaz, représentant de la région d'Antofagasta, où se trouve l'ELT, a assisté aux Tijerales. À Garching, l'événement comprenait des présentations, de la mise en réseau et un buffet avec ma particiâtion de plusieurs industries ayant participé à la conception, à la construction et à l'intégration des composants de l'ELT. Un flux en direct a été mis en place entre les deux événements, permettant aux équipes des deux continents de partager le succès de la construction de l'ELT, le projet ayant récemment franchi la barre des 60 % d'achèvement.
Cette célébration transatlantique a réuni de nombreuses personnes impliquées dans la construction de l’ELT. Un projet d’une telle envergure n’a pu voir le jour que grâce au soutien constant des États membres et partenaires de l’ESO, ainsi qu’à l’engagement des différents partenaires institutionnels et industriels, sans oublier les nombreuses équipes de l’ESO qui ont œuvré à sa réalisation.
La cérémonie du faîtage serait originaire de l'ancienne Scandinavie et se déroule sur les chantiers de construction du monde entier. La coutume chilienne veut qu'un drapeau soit placé au point le plus haut, tandis que dans de nombreux autres pays (y compris la Richtfest allemande), ce drapeau est remplacé par une couronne, des branches d'arbre ou des guirlandes de feuillage persistant. Malgré leurs différences, la plupart des versions de l'événement prévoient un repas bien mérité pour celles et ceux qui ont directement été impliqués dans le projet de construction.
Alors que la construction du plus grand œil du monde sur le ciel se poursuit, nous nous réjouissons de célébrer les prochaines étapes sur le chemin de la première lumière. Une fois opérationnel, l'ELT de l'ESO observera le cosmos depuis un endroit unique sur Terre. Grâce à ses prouesses technologiques et à la pureté du ciel au-dessus d'Armazones, l'ELT révolutionnera notre connaissance de l'Univers.
