NGC 5940 is a barred spiral galaxy located in the Serpens constellation. [1] [2] [3] The galaxy was found on April 19, 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 is considered 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 get ejected into the depths of space.
