Astronomers Unveil the Power and Speed of Cygnus X-1's Black Hole Jets
For the first time, scientists have measured the instantaneous power and speed of jets from the black hole Cygnus X-1. Located 7,200 light-years away, this black hole is part of a binary system with a blue supergiant star. The jets, which are equivalent in power to 10,000 suns, travel at half the speed of light. The research, led by Steve Prabu from the University of Oxford, utilized 18 years of high-resolution radio imaging. The jets are influenced by the stellar wind from the companion star, causing them to bend and wobble. This study, published in Nature Astronomy, marks a significant advancement in understanding black hole dynamics.
