On December 18, 2019, a star in the Large Magellanic Cloud brightened and dimmed symmetrically over one hour, detected by Chilean observatory telescopes. The phenomenon, explained by gravitational microlensing, suggests a very light object (about 3 lunar masses) passed between Earth and the star, ruling out typical stellar black holes.

Government science funding
No immediate consumer impact. Long-term indirect effects possible through increased funding demands for physics research and space observation infrastructure, potentially affecting tax policy or research budget allocation.
May influence government science funding priorities toward dark matter research and astronomical observation infrastructure. Could strengthen arguments for increased investment in space telescopes and research institutions. Potential for international collaboration agreements on space research.
