Le Soleil ne se couchant jamais sur Spitzberg en juin (il brille jour et nuit), l'\u00eele offre \u00e0 l'\u00e9quipe la possibilit\u00e9 unique d'observer l'ensemble du passage. Le passage commencera \u00e0 00h04 (heure avanc\u00e9e d'Europe centrale ou HAEC) et se terminera \u00e0 06h52 HAEC.<\/p>\n<p>Un passage de V\u00e9nus ne se v\u00e9rifie que lorsque V\u00e9nus passe exactement entre le Soleil et la Terre.<\/p>\n<p>Un tel passage est tr\u00e8s rare.

Ils leur ont fournis, par exemple, un moyen pour calculer la taille du syst\u00e8me solaire. Les passages du 18e si\u00e8cle ont \u00e9galement permis aux astronomes de calculer la distance entre la Terre et le Soleil.<\/p>\n<p>Lors du passage de 1761, les astronomes ont remarqu\u00e9 un halo de lumi\u00e8re autour du bord sombre de la plan\u00e8te. C\u2019est ainsi que nous avons d\u00e9couvert que V\u00e9nus poss\u00e9dait une atmosph\u00e8re. Gr\u00e2ce aux sondes spatiales qui se sont rendues depuis sur V\u00e9nus, nous savons aujourd\u2019hui que son atmosph\u00e8re est riche en dioxyde de carbone et en azote, et qu\u2019elle contient des nuages d\u2019acide sulfurique\u2026 ce qui la rend inhospitali\u00e8re !<\/p>\n<p>Pour c\u00e9l\u00e9brer cet \u00e9v\u00e9nement exceptionnel, l'ESA publiera des informations g\u00e9n\u00e9rales sur le transit de V\u00e9nus sur une page d\u00e9di\u00e9e <a href=\"http:\/\/blogs.esa.int\/venustransit\/ \" target=\"_blank\" rel=\"noopener\">blog<\/a>.
