A Glimpse into the Universe's Dawn
After 180 hours of continuous observation, the Chandra telescope achieved an unprecedented technical feat.
A supermassive black hole appears to be exhaling fire at a temperature of 36 million degrees Fahrenheit (approximately 20 million degrees Celsius), revealing a cosmic phenomenon located 11.7 billion light-years from Earth. The event was captured just 2.1 billion years after the Big Bang, the great explosion that gave birth to the universe.
What Is a Quasar?
A quasar is the extremely bright core of a distant galaxy, powered by a supermassive black hole that devours surrounding matter. In this case, the quasar studied lies at the heart of MQN01, a protocluster of galaxies—the embryo of what will become a massive cluster like those we observe today.
The Black Hole's Breath
What the telescope detected is not the quasar itself, but its outflow: a cloud of scorching gas 100,000 light-years across that surrounds it. Over time, this gas will become the intracluster medium (ICM), the hot atmosphere that envelops modern galaxy clusters.
A Historic Technical Achievement
The team had to separate the faint glow of the giant cloud from the blinding glare of gas falling toward the black hole. “The central scientific question is understanding how this hot phase forms,” explained Sebastiano Cantalupo from the University of Milan-Bicocca. He added that cold gas falls into the gravitational potential of this massive halo and is heated by gravitational shocks.
Andrea Travascio, team leader from INAF, admitted they were initially skeptical and analyzed artificial leaks or instrumental contamination, but the thermal explanation turned out to be the only consistent one.
The results were published on July 24, 2026 in the journal Astronomy & Astrophysics. The discovery also pays tribute to the Chandra telescope, which after 25 years in orbit and in the final phase of its mission, continues to produce frontier science. Researchers now aim to determine whether this 36-million-degree inferno is the standard way the universe built its cities of galaxies.
