"Surprising Discovery: Galaxy Comprised Mostly of Mysterious Dark Matter"

A newly discovered dwarf galaxy called Nube, found by chance in images gathered by the IAC Stripe82 Legacy Project, is mostly comprised of dark matter and is the largest ultra-diffuse galaxy known. While it supports the dark matter cosmological model, it doesn't match the profile of the popular variant known as cold dark matter, instead fitting a version called fuzzy dark matter. This finding suggests that there may be more dwarf galaxies made mostly of dark matter in our celestial neighborhood, waiting to be discovered.
