A 4,000-pound astronomy instrument called APOGEE-2, built in the last two years at the University of Virginia, will soon be crated up and transported on an 8,000-mile, two-month journey to its new home at the Las Campanas Observatory in the northern Chilean desert. The instrument – an infrared spectrograph - is designed to peer through cosmic dust to stars at the farthest reaches of our home galaxy, the Milky Way.
