Depuis un mois environ, la plan\u00e8te Mars<\/a> s’approche progressivement de la lettre G que les \u00e9toiles les plus brillantes de l’hiver dessinent<\/a> dans le ciel hivernal. Mais le 20 janvier 2025, vous pourrez constater que la plan\u00e8te rouge participe \u00e0 son trac\u00e9, comme Jupiter<\/a> ! Elle continuera ensuite son chemin \u00e0 l’int\u00e9rieur du G apr\u00e8s cette date.<\/p>\n\n\n\n

C’est un magnifique ensemble d’\u00e9toiles et de plan\u00e8tes \u00e9tincelantes qui s’\u00e9talent de l’horizon jusqu’au z\u00e9nith lorsque vous vous tournez vers le sud, en d\u00e9but de nuit en janvier et f\u00e9vrier. Cette r\u00e9gion du ciel est d’autant plus belle qu’elle est travers\u00e9e par la Voie lact\u00e9e d’hiver. La trouver est simple : elle se trouve au sud vers 22h fin janvier et vers 21h fin f\u00e9vrier.<\/p>\n\n\n\n

Si vous ne l’avez pas encore fait, r\u00e9visez vos constellations ainsi que les noms des \u00e9toiles les plus lumineuses \u00e0 l’aide de l’illustration l\u00e9gend\u00e9e ci-dessous. Un petit travail d’identification facile \u00e0 faire \u00e0 l’\u0153il nu, m\u00eame en ville (\u00e0 condition que votre horizon sud soit d\u00e9gag\u00e9).<\/p>\n\n\n
