3C 305, also known as IC 1065, is a lenticular galaxy located in the constellation Draco.[3][1] The galaxy is located 577 million light-years away from Earth. [2] It has an active galactic nucleus and is classified as a Seyfert 2 galaxy.[1][2] This galaxy was discovered by American astronomer Lewis Swift when he came upon it on April 7th, 1888.[4]

3C 305 is also a radio galaxy.[5][6] It shows an extended X-ray halo previously detected by Chandra X-ray and Very Large Array observations and hydrogen outflow with a jet power of ∼1043 erg s-1.[7]

In additional, 3C 305 shows broad HI absorption levels, which researchers interpreted it as jet-cloud interaction.[8] There are also signs that 3C 305 might be involved in a recent merger process with another gas-rich galaxy.[9]

One supernova has been observed in the galaxy so far: SN 2003jb, (type Ia, mag. 16.5), discovered in December 2003.[10][11]
