Despite its size (only 60 stars 10 light-years away), UMa3/U1 remained undetected for a very long time. The question is whether this is a true dwarf galaxy or a star cluster on the verge of collapse. Perhaps the answer lies in dark matter, the invisible substance thought to hold galaxies together. If UMa3/U1 is a dwarf galaxy, its survival could be explained by the abundance of dark matter that acts as cosmic glue. This discovery will be revolutionary and will reveal the existence of many invisible galaxies dominated by dark matter.
Alternatively, UMa3/U1 may be a star cluster nearing its end, offering a rare chance to observe the disintegration process firsthand.
