The benefits of this wide-angle, time-lapse approach are familiar in natural science. Early astronomy began studying the universe in a single band of radiation—visible light—at one point in time, viewing the night sky through a telescope. Later astronomers began to study the sky over longer periods of time, and to measure the entire electromagnetic spectrum, creating infrared astronomy, X-ray astronomy, and so on. Recently, multispectral astronomy has emerged, allowing images from separate spectra to be integrated and observed over longer periods of time. For example, our contemporary
