Climats, eau, vie : la Terre, une exception dans l'Univers?

This simulated live view of the solar system allows you to explore the planets, their moons, asteroids, comets and the spacecraft interacting with them in 3D. You can also fast-forward or rewind time, and explore the solar system as it looked from 1950 to 2050, complete with past and future NASA missions. You can follow over 150 NASA missions from start to finish with this browser-based 3D simulation that uses the most accurate data and imagery possible. Watch the Voyager spacecraft from launch in 1977 until today, see the Cassini mission fly through the ice plumes of Enceladus, ride along as OSIRIS-REx lands on an asteroid to scoop up material, see the New Horizons mission take the first close pictures of Pluto, witness the first Artemis mission circle the moon, or preview the Europa Clipper mission.

Cette fiche comprend une grille d'écoute et des questions de compréhension en lien avec l'épisode 3 du balado « ASTRO-BIEN ». Michel Vadeboncœur reçoit à son agence la famille Bourdon, habituée aux tout inclus des destinations Soleil. Le vendeur de voyages intergalactiques a exactement ce qu’il leur faut : un forfait vacances sur l’étoile Trappist-1 et ses sept exoplanètes! Les Bourdon pourraient devenir les premiers à visiter le système Trappist, ses océans de magma et ses volcans en éruption, le tout à des années lumières de notre système solaire…

Explore over 5,500 confirmed exoplanet systems in this 3D interactive simulation. You can visit every exoplanet ever discovered and ride along with the spacecraft that found them. The app is constantly updated for the latest discoveries, and you can visit any system, compare it to our solar system, and see if any of the planets reside in the "habitable zone", indicating a possibility of life. Browse by planet type, detection method, or observatory, or see just the discoveries made by the Kepler and TESS missions. You can land on Earth and see a map of all the known exoplanets from your hometown.
