CAPE CANAVERAL, Fla. — For the first time, scientists have measured the incredible power of jets being ejected from a black hole. This research team, featuring experts from the University of Oxford, found that the jet power from the black hole Cygnus X-1 is equivalent to 10,000 suns.
The exciting part? These jets travel at about 355 million miles per hour—roughly half the speed of light.
Cygnus X-1 sits 7,200 light-years away in the Cygnus constellation and consists of a black hole and a blue supergiant star. This black hole was the first one ever identified, making its discovery in the 1960s significant in the study of astrophysics.
Steve Prabu, who led the study, and his team used 18 years of high-resolution data from a global network of telescopes to arrive at their conclusions, published in Nature Astronomy. Prabu refers to the jets as “dancing jets,” which shift direction due to the wind from the nearby star.
Prior methods of measuring a black hole’s jet power took thousands of years to average results. However, this team found that around 10% of the energy released as matter falls into the black hole is carried away by the jets. This is an important insight into the energy dynamics at play around black holes.
The supergiant star supplies gas to the black hole, which helps create the jets. By studying these jets, scientists hope to learn more about how black holes influence galaxies and cosmic structures through immense shocks and turbulence.
Prabu is eager to apply these methods to other black holes in the future, stating that it would be thrilling to measure jet power across different systems.
Understanding black holes and their jets is essential not just for astrophysics but for understanding the very fabric of our universe. As technology advances, we may uncover even more secrets about these intriguing cosmic giants.
