Gaia detects planets in the act of forming — astrometric hints in 31 of 98 young systems
ESA's Gaia has measured the tiny gravitational wobbles of unseen companions inside protoplanetary disks, revealing candidate planets, brown dwarfs and stellar companions in 31 of 98 young systems surveyed. The result shows astrometry can probe dust‑shrouded, embedded formation stages previously considered nearly unobservable.
