Story summary

Astronomers are investigating the black hole IGR J17091-3624, situated 28,000 light-years from Earth, noted for its rhythmic brightness.
NASA's IXPE detected a 9.1% polarization degree, challenging current black hole environment theories.
Two models explain the observations: one involves winds from the accretion disk, the other suggests rapid corona movement.
Findings were published on May 27 in the Monthly Notices of the Royal Astronomical Society.
