Story summary

Tel Aviv University researchers report the first stars in the early Universe likely formed in binary systems.
The Binarity at LOw Metallicity (BLOeM) survey used James Webb Space Telescope data to study 150 massive stars in the Small Magellanic Cloud.
The study finds that at least 70% of these stars are in close binary systems.
This result shows how Population III stars enriched galaxies and shaped supermassive black hole formation.
