C’est en \u00e9tudiant une cha\u00eene de 8 galaxies \u00e0 cheval entre les constellations de la Vierge et de la Chevelure de B\u00e9r\u00e9nice que l’astronome arm\u00e9nien Benjamin Markarian (1913-1985) d\u00e9couvrit en 1961 qu’elles \u00e9taient li\u00e9es physiquement puisque l’\u00e9tude de leur spectre trahissait un mouvement identique dans l’espace.<\/p>\n

Il s’agit de M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 et NGC 4435. Les deux plus brillantes (M 84 et M 86) ont \u00e9t\u00e9 catalogu\u00e9es par l’astronome fran\u00e7ais Charles Messier<\/a> \u00e0 la fin du XVIIIe si\u00e8cle, les 6 autres ont \u00e9t\u00e9 r\u00e9f\u00e9renc\u00e9es ult\u00e9rieurement dans le New General Catalog of Nebulae and Clusters of Stars<\/em> (NGC) \u00e9tabli par John Dreyer \u00e0 la fin du XIXe si\u00e8cle.<\/p>\n
