Webb's First Deep Field (NIRSpec Emission Spectrum)

This galaxy emitted its light 13.1 billion years ago. It was captured by Webb’s microshutter array, part of its Near-Infrared Spectrograph (NIRSpec). This instrument is so sensitive that it can observe the light of individual galaxies that existed in the very early universe. This will prove transformational for research. Webb’s capabilities have allowed scientists to observe spectra of galaxies this far away for the first time.
