NGC 3414
NGC 3414 is a lenticular galaxy in the constellation Leo Minor (constellation), Leo Minor. It was discovered by William Herschel on April 11, 1785. It is the central galaxy of a rich galaxy group. Two galaxies, NGC 3418 and UGC 5958, have similar cosmological redshift, redshifts and are within 800,000 light-years (250 kiloparsecs) of NGC 3414. It is a member of the NGC 3504 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster. It has a peculiar galaxy, peculiar morphology, and is listed in Halton Arp's Atlas of Peculiar Galaxies as Arp 162. The outer disc is nearly face-on, and the inner disk has a higher ellipticity and perhaps a central bar. There is a radio source that is powered by a central active galactic nucleus.

Dark Energy Spectroscopic Instrument
The Dark Energy Spectroscopic Instrument (DESI) is a scientific research instrument for conducting spectrographic astronomical surveys of distant galaxies. Its main components are a focal plane containing 5,000 fiber-positioning robots, and a bank of spectrographs which are fed by the fibers. The new instrument will enable an experiment to probe the expansion history of the universe and the mysterious physics of dark energy. The instrument is operated by the Lawrence Berkeley National Laboratory under funding from the US Department of Energy's Office of Science. Construction of the new instrument, now completed, was principally funded by the US Department of Energy's Office of Science, and by other numerous sources including the US National Science Foundation, the UK Science and Technology Facilities Council, France's Alternative Energies and Atomic Energy Commission, Mexico's National Council of Science and Technology, Spain's Ministry of Science and Innovation, by the Gordon ...
