The peculiar discovery could represent a new class of impossibly faint, dark-matter-dominated star systems that had eluded detection until now. Tentatively named Ursa Major III/UNIONS 1 (UMa3/U1), the newfound star system resides in the constellation of Ursa Major, about 30,000 light years from the Sun. It’s the newest addition to our galaxy’s assortment of at least 50 satellite galaxies. Even the smallest of these galaxies host thousands to billions of stars.

The Space Force is launching lasers into orbit
The Space Force aims to better pinpoint the location of Earth's true centre using lasers on GPS satellites, slated to launch in 2025. A set of Laser Retroreflector Arrays, or LRAS, will be installed onto two GPS III satellites, SV9 and SV10, as part of NASA's Space Geodesy Program. The lasers are designed to make precise sub-centimetre measurements using a technique called Satellite Laser Ranging, which will allow researchers to more accurately determine Earth's centre.
