SMRTR summary
Scientists using data from NASA's TESS satellite, Europe's Gaia spacecraft, and the Sloan Digital Sky Survey discovered that the famous Pleiades star cluster, known as the "Seven Sisters," actually contains over 3,000 associated stars spread across 1,950 light-years. By combining stellar motion, rotation, and chemical data from these three sources, researchers at the University of North Carolina and Carnegie Institution revealed the cluster extends much farther than previously thought, prompting them to rename it the Greater Pleiades Complex.
