NGC 5929 is a well-studied[8] Seyfert galaxy in the constellation Boötes.[9][10] It was discovered by English astronomer John Herschel on May 13, 1828.[11] In the revised New General Catalogue it is described as "elongated, brighter toward the middle, with a slightly diffuse halo". This galaxy is located at an estimated distance of 133 million light-years (40.8 megaparsecs).[3] It forms an interacting pair[12] with NGC 5930 at an angular separation of 0.5′; together they form entry number 90 in Halton Arp's 1966 Atlas of Peculiar Galaxies.[13] A dust streak from NGC 5930 appears to lie in front of NGC 5929, suggesting that the former galaxy is the closer member of this pair.[6]

The morphological classification of NGC 5929 is Sab,[6] indicating this is a spiral galaxy with tightly wound spiral arms. It has a Seyfert 2 nucleus with a bi-polar radio jet oriented along a position angle of ~60°.[14] This galaxy is a radio source having a double-lobe structure, with each lobe showing an emission region counterpart in the optical band.[10][15] When observing the double-ionized oxygen line, each lobe is found to display a velocity component. The peaks of both the radio emission and velocity component are aligned.[8]
