Herein we learn about the nature of full-sky surveys. It is highly instructive to make maps of the entire sky, just like it's important to make maps of our spherical Earth. We look at many wavelength bands and how the sky looks at all those wavelengths. This is part of my intro Astronomy class taught at Willam Paterson University and CUNY Hunter.
