Image dans les ondes radio de la fr:galaxiefr: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.

Plasma jet observed in interferometry in the galaxy M87. The effect is attributed to the intense magnetic field near the rotating supermassive black hole M87* located at its center
Jet de plasma observé en interférométrie dans la galaxie M87. L’effet est imputé au champ magnétique intense à proximité du trou noir supermassif en rotation M87* situé en son centre
