About this Image

False color image of the radio jets from the radio galaxy NGC 1265. Red shows regions of intense radio emission, while blue shows regions of fainter emission. The center of the radio galaxy is at the location of the red circle at the bottom center of the image. This source is the prototype for the class of Narrow Angle Tail radio sources. The galaxy is moving through the intergalactic medium of the Perseus Cluster at a velocity of about 2000 km/s. It is thought that twin beams of plasma ejected from the galactic nucleus are bent by the ram pressure exerted by the external gas, producing the 'U' shape.
