A Tenuous Diffuse Galaxy

The ultra-diffuse galaxy GAMA 526784 appears as a tenuous patch of light in this image. This wispy object resides in the constellation Hydra, roughly four billion light-years from Earth. Ultra-diffuse galaxies such as GAMA 526784 have a number of peculiarities. For example, their dark matter content can be either extremely low or extremely high. Ultra-diffuse galaxies have been observed with an almost complete lack of dark matter, and others consist of almost nothing but dark matter. Another oddity of this class of galaxies is their anomalous abundance of bright globular clusters, something not observed in other types of galaxies.
