Astronomical telescopes can’t help viewing the past.. . Distance and time are always mixed in astronomical observations.. The finite speed of light means that we always see things after they have happened–a delay of 8 minutes for the Sun and about 12 billion years for the most distant galaxies we can observe. In other words,. With a wide-field multi-IFU spectrograph. Cluster studies. Clusters provide large samples of galaxies in a moderate field. Unique perspective on the interaction of galaxies with their environment. As they operate much as a closed box, they are useful as tracers of galaxy evolution and of cosmology. vs. Creation.
