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.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
