Black Hole "Blast" Reaches 300,000 Light Years
Researchers using the XRISM satellite have discovered that winds from supermassive black holes are significantly more powerful than previously estimated, extending up to 300,000 light-years. This turbulence impacts the surrounding galaxy cluster with energy equivalent to billions of supernova explosions.
Why it matters
This discovery fundamentally changes the scientific understanding of how black holes influence the evolution and structure of galaxies beyond their immediate vicinity.
A team of researchers has discovered that the winds generated by supermassive black holes are 100 times more powerful than previously thought, carrying energy across distances of approximately 300,000 light-years. The discovery demonstrates that these explosive winds impact the vast expanse of space beyond the galaxies they inhabit.
"Black holes are largely known for sucking matter in, but they also eject gas in the form of powerful winds," says Satoshi Yamada, Assistant Professor at Tohoku University's Frontier Institute for Interdisciplinary Sciences (FRIS). "These winds were thought to be contained within the galaxy, but our study revealed that the force is immensely more powerful than previously understood."
