Suspens pour le\u00a0Thirty Meters Telescope<\/em> dont la construction au sommet du Mauna Kea pourrait \u00eatre refus\u00e9e par la Cour Supr\u00eame d’Hawaii.<\/strong><\/p>\n

Quatre t\u00e9lescopes g\u00e9ants annoncent une r\u00e9volution dans le monde de l’astronomie pour les deux prochaines d\u00e9cennies. Il y a d’abord le nouveau t\u00e9lescope spatial, le James Webb Space Telescope<\/em> ou JWST<\/a>, dont la totalit\u00e9 des 18 segments qui forment le miroir primaire sont d\u00e9sormais assembl\u00e9s et qui va maintenant subir une s\u00e9rie de tests avant son lancement en octobre 2018.<\/p>\n

Au sol ce sont trois t\u00e9lescopes g\u00e9ants qui vont sortir de terre\u00a0: le T\u00e9lescope G\u00e9ant Magellan (GMT<\/a>) dans le d\u00e9sert d\u2019Atacama au Chili, l\u2019E-ELT<\/a> (pour European Extremely Large Telescope<\/em>) construit \u00e9galement au Chili par l\u2019ESO et le TMT<\/a> (pour Thirty Meters Telescope<\/em>).<\/p>\n

\"tmt1\"<\/a><\/p>\n

Soutenu principalement par les USA, le TMT est comme son nom l’indique un t\u00e9lescope qui sera \u00e9quip\u00e9 d’un miroir segment\u00e9 de 30 m\u00e8tres de diam\u00e8tre muni d’une optique adaptative<\/a> (pour corriger les imperfections g\u00e9n\u00e9r\u00e9es par la turbulence atmosph\u00e9rique) et pourra observer l’Univers depuis le proche ultraviolet jusqu’\u00e0 l’infrarouge moyen.<\/p>\n

Initialement le TMT devait prendre place au sommet du Mauna Kea<\/a> sur l’\u00eele d’Hawaii comme c’est d\u00e9j\u00e0 le cas de plusieurs instruments (dont le T\u00e9lescope Canada-France-Hawa\u00ef) regroup\u00e9s au sein de l’Observatoire du Mauna Kea.<\/p>\n

Mais les opposants au projet (\u00e9cologistes qui s’inqui\u00e8tent pour l’environnement et peuples autochtones pour qui le volcan endormi est une montagne sacr\u00e9e) sont d\u00e9termin\u00e9s \u00e0 utiliser toutes les proc\u00e9dures possibles pour annuler la construction de l’instrument. Ils ont m\u00eame obtenu une premi\u00e8re victoire en d\u00e9cembre 2015 lorsque la justice a demand\u00e9 aux promoteurs de soumettre une nouvelle demande de permis.<\/p>\n

\"tmt2\"<\/a><\/p>\n

Gel\u00e9 depuis pr\u00e8s d’un an, le projet repasse ce mois-ci devant la Cour supr\u00eame d’Hawaii. Prudents, les membres du Conseil du TMT r\u00e9unis fin octobre ont annonc\u00e9 que l’instrument pourrait finalement \u00eatre construit aux Canaries<\/a> si son implantation \u00e9tait impossible au sommet du Mauna Kea. Bien qu’un peu moins bon que celui d’Hawaii, le ciel des Canaries est l’un des meilleurs de l’h\u00e9misph\u00e8re nord. Les \u00eeles espagnoles accueillent d\u00e9j\u00e0 l’ Observatoire du Roque de los Muchachos<\/a> (ou se trouve le Gran Tecan<\/a>) et l’Observatoire du Teide<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
