NGC 5940 is a barred spiral galaxy located in the Serpens constellation.[1][2][3] The galaxy was found on 19th April in 1887 by Lewis Swift, an American astronomer.[2] NGC 5940 is located 500 million light-years away from the Milky Way and it is approximately 140,000 light-years across in diameter.[3][2]
NGC 5940 is a Seyfert type 1 galaxy and considered as a quasar according to the SIMBAD database.[4][5] It is registered under the Markarian Catalogue as Markarian 1511 or MRK 9030.[6] It has an bright active core, meaning there is a presence of an acceleration disc around its huge black hole. This in turn, emits strong radiation and ultraviolet rays that later gets ejected into the depths of space.
