NASA solves Black Hole Jet mystery with IXPE: Compton scattering confirmed as X-Ray source
Science | May 12, 2025, 09:46 AM ISTNASA’s Imaging X-ray Polarimetry Explorer (IXPE) has solved a long-standing cosmic mystery about how X-rays are generated in the powerful jets of black holes like blazar BL Lacertae. By observing low X-ray polarisation alongside high optical polarisation, the findings point to Compton scattering.

Scientists record spectacular flares produced by collisions of two black holes
Science | Jun 28, 2020, 10:43 AM ISTA spectacular discovery of light flares produced by a collision between 2 black holes has been made by scientists of US universities. The discovery is groundbreaking because black holes are regions of spacetime where the gravitational force is so strong that not even light can escape, this means that if two black holes collide they should not emit light.
