Astronomers have tested the new Vera C. Rubin telescope in Chile, much like adjusting the focus and aperture on a brand-new camera. The first images covered a patch of sky the size of 60 full Moons, and immediately revealed millions of galaxies and stars. The imaging was done in various colors, from invisible ultraviolet to thermal infrared.

A distant lamp shines through uneven glass. The glass bends the rays, and instead of one flame on the wall, several appear — some brighter, some fainter. In much the same way, a massive galaxy bends the light of an exploded star. There was one explosion, but the images show four glowing points.
