Le rover Curiosity de la NASA a découvert les plus longues chaînes de molécules de carbone jamais trouvées sur Mars : une étape majeure dans la recherche de vie extraterrestre
Le rover Curiosity de la NASA a détecté les plus grandes molécules organiques jamais identifiées sur la planète rouge, dans une roche vieille de 3,7 milliards d’années. Cette découverte relance les espoirs de trouver des signes de vie passée sur Mars, notamment dans le cadre de futures analyses sur Terre. Bien que leur origine reste incertaine, ces molécules complexes pourraient être des fragments d’acides gras, similaires à ceux présents dans les membranes cellulaires terrestres.
