Astronomers have captured striking new details of powerful jets shooting out from a black hole, revealing just how much energy these cosmic systems can release.
In a study led by Curtin University and published in Nature Astronomy, scientists found that the jets from the famous black hole system Cygnus X-1 produce energy equal to about 10,000 suns.
Cygnus X-1 is one of the most well-known black hole systems ever discovered. It includes a black hole and a massive companion star that orbits closely around it.
As material from the star falls toward the black hole, some of that energy is not swallowed. Instead, it is blasted outward in narrow, high-speed jets that shoot into space.
To study these jets, researchers used a network of radio telescopes spread across the Earth, effectively creating a giant telescope. This allowed them to capture detailed images of how the jets behave over time.
What they saw was unusual and fascinating. The jets appeared to “dance,” constantly shifting direction as they were pushed around by strong winds coming from the nearby supergiant star.
This movement turned out to be the key to measuring their power. By understanding how strong the star’s winds were and observing how much they bent the jets, the scientists could calculate how much energy the jets carried.
This is the first time researchers have been able to measure the power of black hole jets in real time, rather than averaging it over very long periods.
The team also measured how fast the jets are moving. They found that the streams of matter travel at about half the speed of light, which is roughly 150,000 kilometers per second. This is an incredibly high speed and confirms long-standing theories about how energetic these jets can be.
Another important discovery is how much of the black hole’s energy ends up in these jets.
The study shows that around 10 percent of the energy released as matter falls into the black hole is redirected outward through the jets. Scientists have often assumed this value in computer models of the universe, but until now, it had been difficult to confirm with direct observations.
Understanding this process is important because black hole jets do not just stay near the black hole. They can travel vast distances and affect the space around them, including gas clouds where new stars may form. In this way, black holes can play a major role in shaping entire galaxies.
The findings also come at an exciting time for astronomy. New projects like the Square Kilometer Array Observatory are being built and will allow scientists to detect black hole jets in millions of distant galaxies. With this new measurement as a reference point, researchers will be better able to understand and compare these powerful cosmic phenomena.
This study offers a clearer picture of how black holes interact with their surroundings, showing that even objects known for pulling everything in can also send enormous amounts of energy back out into the universe.
