First DESI Spectrograph Delivered to Kitt Peak Telescope

23 Julio 2018

Light from a flashlight is dispersed into a spectrum by one of the spectrographs that will be integrated into the Dark Energy Spectroscopic Instrument (DESI) at the 4-m Mayall telescope. Designed to acquire spectra of 5000 astronomical objects simultaneously, DESI will be equipped with ten three-armed spectrographs. DESI will explore the mysterious physics of dark energy, which is believed to accelerate the expansion of the Universe.
