NASA spots unexpected X-ray polarization in Heartbeat black hole, hinting at extreme cosmic winds or rapid plasma jets

Astronomers are intrigued by a black hole named IGR J17091-3624. It is located 28,000 light-years away. NASA's IXPE observed its rhythmic brightening and dimming. The black hole's X-ray signals are unusual. The corona's polarization degree is surprisingly high. Researchers are testing models to explain these odd readings. Future observations may reshape our understanding of black holes.
