Which spectral range does the SPHEREx spectrometer utilize to observe the sky?
Answer
Near-infrared
The spacecraft is equipped with a spectrometer that operates in the near-infrared range, specifically between 0.75 and 5.0 micrometers. This range is scientifically vital because it allows the instrument to peer through the dense dust clouds of the Milky Way, which would otherwise obscure observations in visible light. This capability is essential for creating a complete map of the galaxy's composition.
