Free-floating planets, untethered to stars, long remained a mystery: without an exact distance, their mass couldn't be measured. By combining telescopes on Earth and in space, scientists calculated the distance to object KMT-2024-BLG-0792 and found its mass—just 0.22 Jupiter masses. It turned out to

Astronomers have reported the discovery of four cold giant planets around low-mass stars. They were betrayed by brief anomalies in the light curves — as if a water droplet on a windowpane momentarily focused distant light. All planets lie beyond the snow line, up to 6 astronomical units from their s
