Blue Nugget (also called BN) galaxies are a type of distant galaxy that only existed in the early universe. Blue nugget galaxies are small but high mass galaxies undergoing mass bursts of star formation, making many large, bright blue stars. As their stellar population evolves and ages, blue nugget galaxies transition into red nugget galaxies.[1]
"Blue" derives from their blue coloration and "Nugget" derives from their small size.[2]
Examples of Blue Nugget galaxies:

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.
