Les photos que nous avons le plaisir de vous présenter dans cette carte de voeux proviennent de la Nasa (administration américaine de l'aéronautique et de l'espace). Elles ont toutes été prises depuis l'espace et, pour certaines, par les astronautes de la station spatiale internationale. Vous trouverez chacune des photos agrandie en suivant le lien au début de chaque repère.
Pour certaines, nous avons ajouté un lien vers des informations disponibles sur Waternunc.com.
