Summary

Story summary

Telescope observations in Chile showed black hole Swift J1727.8–1613 expelled mass roughly equal to what it consumed.
The team observed an outward gas storm accounting for at least 10% of the transferred mass.
Researchers found about half of the star’s material never entered the black hole, implying expelled mass may equal the consumed mass.
Kyle Solomons reported gas expulsion persisted after X-ray emission fell to a fraction of its peak.
