NASA Discovers Record-Breaking Supermassive Black Hole Over 13 Billion Light-Years Away

Astronomers found the most distant black hole ever detected in X-rays (in a galaxy dubbed UHZ1) using the Chandra and Webb space telescopes. X-ray emission is a telltale signature of a growing supermassive black hole. This result may explain how some of the first supermassive black holes in the universe formed. These images show the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from Webb, as well as close-ups of the black hole host galaxy UHZ1.

NASA Telescopes Discover Record-Breaking Black Hole

This image reveals the most remote black hole ever identified through X-rays, potentially shedding light on the formation of the earliest supermassive black holes in the cosmos. This discovery was made using X-rays from NASA’s Chandra X-ray Observatory (depicted in purple) and infrared data from the James Webb Space Telescope (shown in red, green, blue).

Galactic Distances and Observations

The extremely distant black hole is located in the galaxy UHZ1 in the direction of the galaxy cluster Abell 2744. The galaxy cluster is about 3.5 billion light-years from Earth. Webb data, however, reveal that UHZ1 is much farther away than Abell 2744. At some 13.2 billion light-years away, UHZ1 is seen when the universe was only 3% of its current age.

Gravitational Lensing and X-ray Detection

By using over two weeks of observations from Chandra, researchers were able to detect X-ray emission from UHZ1 — a telltale signature of a growing supermassive black hole in the center of the galaxy. The X-ray signal is extremely faint and Chandra was only able to detect it — even with this long observation — because of the phenomenon known as gravitational lensing that enhanced the signal by a factor of four.

Imaging Techniques and Orientation

The purple parts of the image show X-rays from large amounts of hot gas in Abell 2744. The infrared image shows hundreds of galaxies in the cluster, along with a few foreground stars. The insets zoom into a small area centered on UHZ1. The small object in the Webb image is the distant galaxy UHZ1 and the center of the Chandra image shows X-rays from material close to the supermassive black hole in the middle of UHZ1. The large size of the X-ray source compared to the infrared view of the galaxy is because it represents the smallest size that Chandra can resolve. The X-rays actually come from a region that is much smaller than the galaxy.

Different smoothing was applied to the full-field Chandra image and to the Chandra image in the close-up. Smoothing across many pixels was performed for the large image, to highlight the faint cluster emission, at the expense of not showing faint X-ray point sources like UHZ1. Much less smoothing was applied to the close-up so faint X-ray sources are visible. The image is oriented so that north points 42.5 degrees to the right of vertical.

Significance of the Discovery

This discovery is important for understanding how some supermassive black holes — those that contain up to billions of solar masses and reside in the centers of galaxies — can reach colossal masses soon after the Big Bang. Do they form directly from the collapse of massive clouds of gas, creating black holes weighing between about ten thousand and a hundred thousand suns? Or do they come from explosions of the first stars that create black holes weighing only between about ten and a hundred suns?

Research Findings and Theoretical Implications

The team of astronomers found strong evidence that the newly discovered black hole in UHZ1 was born massive. They estimate its mass falls between 10 and 100 million suns, based on the brightness and energy of the X-rays. This mass range is similar to that of all the stars in the galaxy where it lives, which is in stark contrast to black holes in the centers of galaxies in the nearby universe that usually contain only about a tenth of a percent of the mass of their host galaxy’s stars.

The large mass of the black hole at a young age, plus the amount of X-rays it produces and the brightness of the galaxy detected by Webb, all agree with theoretical predictions in 2017 for an “Outsize Black Hole” that directly formed from the collapse of a huge cloud of gas.
