Au cours des 30 derni\u00e8res ann\u00e9es, l\u2019Europe a \u00e9t\u00e9 l\u2019un des leaders de l\u2019envoi de sondes pour l\u2019exploration du Syst\u00e8me solaire et de l\u2019Univers. L\u2019on peut citer parmi les moments-clous de cette activit\u00e9 la rencontre avec la com\u00e8te de Halley en 1986, le parachutage d\u2019une sonde sur la Lune Titan de Saturne en 2005 et la d\u00e9couverte d\u2019eau sous forme de glace sous la surface de Mars. D\u2019autres missions de l\u2019ESA \u00e9tudient V\u00e9nus et le Soleil de mani\u00e8re bien plus d\u00e9taill\u00e9e que jamais auparavant et nous livrent des images impressionnantes de galaxies lointaines.<\/p>\n<\/div>\n

Explorer le Soleil constitue depuis toujours une grosse partie du programme de sciences spatiales de l\u2019ESA. Le Soleil apporte la chaleur et l\u2019\u00e9nergie dont tous les \u00eatres vivants ont besoin pour se former et se d\u00e9velopper sur Terre. Sans lui, notre plan\u00e8te serait gel\u00e9e et sans vie.<\/p>\n

Spacecraft built in Europe have been very successful at looking at the Sun and exploring all around it. Some examples of these are:<\/p>\n

    A project between ESA and NASA called Ulysses, which has given us the first-ever map of the heliosphere (the area occupied by the Sun\u2019s magnetic field), from the Sun\u2019s equator to its poles<\/p>\n<\/li>\n

    SOHO, un satellite stationn\u00e9 \u00e0 1,5 millions de km de la Terre, envoie des images des explosions qui se produisent \u00e0 la surface du Soleil et en explore l\u2019int\u00e9rieur<\/p>\n<\/li>\n
