A new instrument designed, built and operated by University of Pennsylvania astronomer James Aguirre, with collaborators at the California Institute of Technology, Jet Propulsion Laboratory and University of Colorado, is helping to open new views on a vital epoch of star formation in the early universe, using a convenient natural phenomenon called gravitational lensing. The instrument is Z-Spec.
