This is 1/1000th of the Rubin telescope's field of view. How many galaxies do you see? There are three really obvious ones. Looking more closely, you could find a dozen more that are recognizably galaxy-ish. But really? It's likely that EVERY LITTLE DOT AND SMUDGE is a distant galaxy. All of them. 🤯
A screenshot from the Rubin telescope image explorer page. The image is of three large-ish galaxies (one elliptical, one spiral, and one blue-ish irregular) and a LOT of little fuzzy dots and smudges of various size scattered across the field of view. At the bottom is a label saying "You are looking at ~1/1,000 of Rubin's field of view" and there are some image controls on the edges.
