Magellanic Clouds
In 2019, astronomers discovered the young star cluster Price-Whelan 1 using "Gaia" data. The star cluster has a low metallicity and belongs to the leading arm of the Magellanic Clouds. The existence of this star cluster suggests that the leading arm of the Magellanic Clouds is 90,000 light-years away from the Milky Way—closer than previously thought.
