Studying billions of objects at once is so fetch! ...okay, we'll stop trying to make fetch happen.

The NSF–DOE Vera C. Rubin Observatory will image billions of stars and galaxies across the entire Southern sky, night after night, because it's what scientists call a “survey telescope”—but what does that mean?

Survey telescopes map the cosmos using all-purpose images, rather than targeted observations — like choosing a wide-angle lens for your camera instead of a telephoto lens.
