The traces of a radio jet from the NGC 1275 galaxy nucleus are revealed in position angle (PA) + 45 deg using the data of published observations at 18, 20, and 73 cm wavelengths. The jet has a distorted form and is seen at 6-7 arcmin distance from the nucleus where its PA = + 20 deg. It is shown that the optical detail situated 7 arcsec north-east from the nucleus of the galaxy is projected exactly on the trace of the radio jet. It is supposed that radio jet is connected with this optical detail, a group of stars. Three radio jets in the circumstellar region of the NGC 1275 galaxy are compared: the youngest in PA = 149 deg, the older in PA = -15 and + 145 deg, with the centers of star formations in a 6 arcsec circumnuclear region. Their ages differ as the ages of corresponding radio jets.
