M106 est une grande galaxie spirale de taille comparable \u00e0 la galaxie d\u2019Androm\u00e8de. Elle est situ\u00e9e dans la constellation des Chiens de chasse \u00e0 une distance de 21 – 25 millions d\u2019ann\u00e9es-lumi\u00e8re.<\/p>\n

\"\"<\/a><\/p>\n

Une de ses particularit\u00e9s est d\u2019\u00eatre constitu\u00e9e de deux paires de bras spiraux. En plus d\u2019une paire classique peupl\u00e9e de jeunes \u00e9toiles chaudes et brillantes, elle poss\u00e8de une seconde paire issue du c\u0153ur et form\u00e9e non pas d\u2019\u00e9toiles mais de gaz. Ces bras \u00ab fantomatiques \u00bb seraient dus \u00e0 des ondes de choc chauffant violemment le gaz sur son passage, et sont une preuve indirecte de la pr\u00e9sence d\u2019un trou noir supermassif log\u00e9 au centre de M106. Cette seconde paire est juste visible en rouge sur la photo, mais bien identifiable par comparaison avec des images prises dans le domaine radio et X (https:\/\/chandra.harvard.edu\/photo\/2007\/ngc4258\/<\/a>). <\/p>\n
