Astronomers have discovered a rogue planet with a mass comparable to Saturn using microlensing techniques. This free-floating planet, detected through gravitational effects on background light, was observed from multiple points on Earth and in space, including data from the Gaia Space Telescope. This allowed for a more accurate measurement of its mass and distance, estimating it to be about 22% of Jupiter's mass and located roughly 3,000 parsecs from the Milky Way's center.
