In brief
- Black hole winds measured by XRISM carry about 100 times more energy than previous estimates.
- The turbulence extends roughly 300,000 light-years, far beyond the black hole's host galaxy.
- The energy involved rivals several billion supernova explosions.
- Researchers observed quasar H1821+643, about 3.4 billion light-years from Earth in the constellation Draco.
- The study, led by Tohoku University's Satoshi Yamada, was published in Nature Astronomy on September 15, 2026.
Winds driven by a supermassive black hole carry roughly 100 times more energy than scientists previously estimated, new observations reveal. The energy in question rivals the output of several billion supernova explosions, and it spreads across some 300,000 light-years — far beyond the galaxy that hosts the black hole.
The finding comes from a team led by Satoshi Yamada, Assistant Professor at Tohoku University's Frontier Institute for Interdisciplinary Sciences (FRIS), working with researchers from Kanazawa University and Tokyo Metropolitan University, among others. Their study, published in the journal Nature Astronomy on September 15, 2026, used data from XRISM, a Japanese X-ray astronomy satellite.
What did the researchers actually measure?
The team pointed XRISM at a quasar called H1821+643, which sits in the constellation Draco about 3.4 billion light-years from Earth.
Quasars are among the brightest objects in the universe. Each one is powered by a supermassive black hole that is actively swallowing gas. As material falls toward the black hole, it releases enormous amounts of energy, making the quasar visible across billions of light-years.
The black hole at the center of H1821+643 sits inside a galaxy cluster — a vast grouping of galaxies bound together by gravity. There, the black hole stirs up the surrounding hot gas, which emits X-rays. To track how that gas was moving, the researchers analyzed emission lines produced by iron ions. An emission line is a specific wavelength of light that a chemical element gives off; shifts and blurring in those lines act like a speedometer for the gas.
XRISM's high-precision measurements showed the extremely hot gas around the black hole is anything but still. Turbulence flings it violently across a broad region. The gas flow extends well past the host galaxy, reaching roughly 300,000 light-years from the black hole. For comparison, our own Milky Way galaxy spans about 100,000 light-years.
Why is this surprising?
Astronomers have long known that black holes do more than devour matter. They also blast gas outward in powerful winds. But the prevailing picture held that these winds stayed largely contained within their host galaxies.
The new data overturn that assumption for this object, at least. The measured energy in the turbulence is about 100 times greater than earlier estimates.
"Black holes are largely known for sucking matter in, but they also eject gas in the form of powerful winds," Yamada said. "These winds were thought to be contained within the galaxy, but our study revealed that the force is immensely more powerful than previously understood."
To put the energy scale in perspective: it is comparable to several billion supernova explosions — the colossal blasts that mark the death of certain stars.
What does this change about our picture of black holes?
The results suggest supermassive black holes play a far more active role in shaping the cosmos than their reputation as cosmic drains implies.
"For the first time, we have shown that black holes influence the broader cosmic environment through a shock wave of astonishing power," Yamada said. "Black holes are key drivers of gas flows and motion in space, transporting vast amounts of energy to different regions of the cosmos."
In practical terms, that means black holes may help redistribute gas and energy across galaxy clusters, potentially shaping the environments in which galaxies live and evolve. Rather than merely consuming what falls into them, they can push material vast distances into surrounding space.
How solid are the numbers?
Some caution is warranted. The measurements come from a single quasar, H1821+643, which sits in an unusually dense and active environment at the heart of a galaxy cluster. It remains to be seen whether winds from other supermassive black holes — especially those in quieter settings — show the same outsized power.
The XRISM observations also represent one snapshot of an ongoing process. Future observations, which the researchers anticipate, should refine the picture of how this energy transport works over time and how matter and elements move between different regions of the cosmos.
Still, the result marks a genuine first. No previous study had directly demonstrated a black hole driving a shock wave of this scale through its cosmic surroundings, according to the team.
The study appears in Nature Astronomy under the title "Vigorous turbulence driven by quasar-mode feedback in a cluster core," with first author Satoshi Yamada and co-authors from institutions including Kanazawa University and Tokyo Metropolitan University.
