TL;DR Summary

Astronomers directly measured the instantaneous power of jets from the Cygnus X-1 black hole binary—nearly 10,000 suns—while jets travel at about 0.5c and bend under the donor star’s wind, based on 18 years of high-resolution radio observations; the real-time jet-power measurement improves understanding of black-hole feedback and its influence on galaxy-scale environments.
