Trous noirs : jets de plasma dans la galaxie M87


Image dans les ondes radio de la fr:galaxie fr:M87, située à 50 millions d'années lumière, dans la fr:constellation de la Vierge (radiotélescop VLA, Février 1989). Un fr:trou noir au centre de la galaxie serait à l'origine des jets de particules dont nous parviennent les ondes radio. Les couleurs faussées correspondent à l'intensité du rayonnement.
