NGC 2090 is a spiral galaxy located approximately 40 million light-years from the Solar System[1] in the Columba constellation. It was discovered on 29 October 1826 by Scottish astronomer James Dunlop.[4] NGC 2090 was studied to refine the Hubble constant to an accuracy within ±10%.[1]

  1. 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.
