Story summary

Researchers led by Andrew Boyle identify the Pleiades as part of the Greater Pleiades Complex, a 3,091-star group spanning 600 parsecs.
The stars share similar ages, chemical compositions, and movement patterns, indicating a common origin from a single giant molecular cloud.
The study used NASA's Transiting Exoplanet Survey Satellite (TESS) and the European Space Agency's Gaia spacecraft.
This approach could trace the Sun's origins and identify its lost stellar siblings.
