Scientists have recently announced an exciting new development in astronomical research: the successful launch of the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4-meter telescope at Kitt Peak National Observatory. The instrument has already collected data from over a million galaxies, and researchers are optimistic that DESI will help us gain a better understanding of the mysteries of dark energy and its implications for our universe. Scientists will use the data from DESI to investigate the expansion history of the universe, as well as the properties of dark energy.
