flag NASA's IXPE mission confirmed that X-rays in a black hole jet come from high-speed electrons colliding with photons, solving a 60-year mystery.

flag NASA's IXPE mission has solved a decades-old mystery by identifying the source of X-rays in a supermassive black hole’s jet within the galaxy 3C 84. flag After 600 hours of observation, IXPE detected a 4% X-ray polarization, confirming that the X-rays result from inverse Compton scattering—where low-energy photons gain energy by colliding with high-speed electrons in the jet. flag Data from Chandra, NuSTAR, and Swift supported this conclusion, ruling out external sources and validating the synchrotron self-Compton model. flag The findings, published November 11, 2025, advance understanding of black hole jet physics and highlight IXPE’s role in probing extreme cosmic environments.
