NGC 5004 is a lenticular galaxy in the constellation Coma Berenices.[1][2] The object was discovered by astronomer William Herschel in 1785, using an 18.7-inch aperture reflector telescope. Due to its moderate apparent magnitude (+13), it is visible only with amateur telescopes or with superior equipment.
One supernova has been observed in NGC 5004: SN 1976A (type unknown, mag. 16.5).[4]

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.
