Black holes are famous for pulling in everything that gets too close, including gas, dust, and even light.
But new research shows they can also blast enormous amounts of energy back into space.
Scientists have now discovered that winds from a supermassive black hole are far more powerful than anyone realized, carrying energy across an astonishing distance of about 300,000 light-years.
The study, published in Nature Astronomy, suggests that these powerful outflows can affect not only the galaxy where the black hole lives but also the vast space surrounding it.
The international research team was led by Satoshi Yamada from Tohoku University’s Frontier Institute for Interdisciplinary Sciences, together with scientists from Kanazawa University and Tokyo Metropolitan University.
“Black holes are largely known for sucking matter in, but they also eject gas in the form of powerful winds,” Yamada explained. Until now, scientists believed these winds mostly stayed inside their host galaxies. The new findings show that the winds travel much farther and carry much more energy than expected.
To make the discovery, the researchers used Japan’s new X-ray astronomy satellite, XRISM, to study a quasar called H1821+643. The quasar is located about 3.4 billion light-years from Earth in the constellation Draco.
A quasar is one of the brightest objects in the universe. Its incredible brightness comes from a supermassive black hole that is rapidly pulling in huge amounts of gas. As the gas spirals toward the black hole, it heats up and releases enormous amounts of energy, making the quasar shine brightly across space.
The black hole at the center of H1821+643 sits inside a large cluster of galaxies. Around it is extremely hot gas that naturally gives off X-rays. By carefully studying X-ray signals from iron atoms within this gas, the scientists were able to measure how the gas was moving with remarkable accuracy.
The observations revealed that the hot gas is far from calm. Instead, it is being stirred into violent turbulence by powerful winds generated by the black hole. These winds push energy far beyond the galaxy itself, reaching distances of roughly 300,000 light-years.
Perhaps the biggest surprise was the amount of energy involved. The team found that the turbulent motion contains about 100 times more energy than previous estimates suggested. The total energy is comparable to the combined force of several billion exploding stars, known as supernovae.
The findings show that supermassive black holes play a much bigger role in shaping the universe than scientists previously understood. Rather than simply consuming nearby material, they also send enormous amounts of energy into surrounding space, influencing the movement of gas across vast cosmic distances.
This flow of energy can affect how galaxies grow, how gas moves between galaxies, and how important elements are spread throughout the universe.
Future observations with XRISM and other advanced space telescopes are expected to reveal even more about how black holes influence the evolution of galaxies and the large-scale structure of the cosmos.
