Every time astronomers have improved their sensitivity to light from the cosmos, or sharpened the quality of images they record, they have discovered a new aspect of the universe.. Advances in instrumentation are now allowing, or will soon allow, astronomers to observe the sky nearly continuously with time sensitivity from a thousandth of a second to, remarkably, a century. I will discuss the instrumentation that make these advances possible, the scientific goals motivating their implementation, and speculate on the unknown unknowns waiting to be discovered.
