Multi-conjugate Adaptive optics Demonstrator (MAD) is an instrument that allowed the European Southern Observatory's Very Large Telescope to observe celestial objects with most of the atmosphere's blurring removed. As with other adaptive optics systems, it works by performing real-time corrections to the atmospheric turbulence by means of computer-controlled deformable mirrors. Its particularity is the correction over a wider field of view than previous systems, which only used a single deformable mirror.[1][2]

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.
