Based on Dong et al. (Science, 2026), who measured a rogue planet's mass for the first time using stereoscopic parallax between Earth and the Gaia spacecraft. A Saturn-mass world, ejected from its birth system, wandering alone 10,000 light-years away — detected only by the light it bends.","shortDescription":"Invisible gravity, bent light"}}
