IC 2448 is an elliptical planetary nebula in the constellation of Carina. It was discovered in 1898 by Williamina Fleming.[3] It lies near the bright star Beta Carinae, and the southern Carina can be explored in the months of autumn in the southern hemisphere.[citation needed] The central star of the planetary nebula is an O-type star with a spectral type of O(H)3 III-V.[4] An analysis of Gaia data suggests that it is a binary system.[5]

  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.
