Scientists have, for the first time, measured the immense power of jets emitted from a black hole, equivalent to the energy of 10,000 suns. This discovery was made in the Cygnus X-1 system, located 7,200 light-years away, which includes a black hole and a blue supergiant star. The jets travel at half the speed of light, about 355 million mph. Researchers used 18 years of radio imaging data to calculate the jets’ power and speed, noting that 10% of the energy from matter falling into the black hole is carried away by these jets. This finding helps scientists understand how black holes influence galaxies and cosmic structures. The study, led by Steve Prabu, was published in Nature Astronomy, and Prabu hopes to apply these techniques to other black holes.
