Astronomers using JWST found surprising "little red dots" in their images. Of course, at those distances, even tiny dots are probably gigantic objects. After further research, these turned out to be supermassive black holes with millions of times the mass of the Sun, seen at a time when the Universe was only a few hundred million years old. They're red because they're surrounded by dust, which obscures the central black hole and reddens the radiation colors.
