Vous avez peut-\u00eatre vu circuler sur les r\u00e9seaux sociaux une image prise par le rover Curiosity, montrant un cercueil pos\u00e9 sur le sol de la plan\u00e8te Mars<\/a> !<\/p>\n

\"mars-cercueil2\"<\/a><\/p>\n

Il s’agit d’une par\u00e9idolie, une sorte d’illusion d’optique : notre cerveau se met \u00e0 associer une image qui nous est famili\u00e8re face \u00e0 une information visuelle ambigu\u00eb.<\/p>\n

En clair, lorsque nous scrutons un champ de cailloux (ou des nuages…), nous croyons “voir” des formes connues, des r\u00e9alisations humaines ou animales.<\/p>\n

Ce n’est pas la premi\u00e8re fois que l’on nous pr\u00e9sente “d’\u00e9tranges” images martiennes. Souvenez-vous du c\u00e9l\u00e8bre “visage<\/a>” photographi\u00e9 par la sonde am\u00e9ricaine Viking 1 en juillet 1976.<\/p>\n

\"visage-mars\"<\/a><\/p>\n

On trouve toujours une explication rationnelle pour ces\u00a0illusions d’optique : images prises \u00e0 la limite de la r\u00e9solution des cam\u00e9ras, ombres particuli\u00e8res selon l’angle d’illumination du Soleil<\/a>, morphologie des terrains…<\/p>\n

De tels clich\u00e9s font en tout cas le bonheur de tous ceux qui sont convaincus depuis longtemps qu’il existe des formes de vie \u00e9volu\u00e9es sur la Plan\u00e8te rouge. Plus raisonnablement, les scientifiques pr\u00e9f\u00e8rent continuer \u00e0 explorer m\u00e9thodiquement le sol du crat\u00e8re Gale<\/a>\u00a0\u00e0 l’aide du rover Curiosity, accumulant les preuves d’un pass\u00e9 chaud et humide sur Mars…<\/p>\n","protected":false},"excerpt":{"rendered":"
