Black holes
[edit]In January 2014, scientists using data collected by the Chandra X-Ray Observatory and other telescopes reported they had found evidence of a new supermassive black hole candidate disrupting a star in a dwarf galaxy in the Abell 1795 cluster.[4][5]

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.
