Scientists discover rare planet at the edge of the Milky Way using space-time phenomenon predicted by Einstein

A rare Jupiter-sized exoplanet, AT2021uey b, was discovered 3,200 light-years away using Einstein's microlensing theory. This planet, the third found far from our galaxy's center, orbits a cool M dwarf star every 4,170 days. The discovery, using Gaia telescope data and confirmed by the Molėtai Observatory, challenges planetary formation models. Microlensing detects planets by observing how their gravity magnifies starlight, enabling the discovery of distant worlds in unexpected locations.
