The Universe’s Earliest Black Hole Dyes Its Home Galaxy a Bright Shade of Red
In the large range of space, the first black hole in the universe was revealed. The black supermassive hole and its domestic galaxy, Capers-LRD-Z9, come from 500 million years after the Big Bang, which means that they have created 13.3 billion years in the past.
A study published in the Astrophysical Journal Details This revolutionary discovery, which could help scientists glean clues to the first universe and the development of black holes. The newly identified black hole is not an ordinary black hole, especially because of its unfathomable age; Its brightness, colossal size and undoubted red shade make it a precious discovery for researchers.
A black hole in cosmic dawn
The black hole of Capers-Lrd-Z9 is like a primordial time capsule of cosmic dawn, an era when the first stars and galaxies began to appear in the universe. It was detected by the James Webb Space Telescope Capers (Candels-Area Prism Epoch of Reionization Survey) program, which searches in the distant universe to learn more about its structure and growth.
To see black holes and stars in the distant universe, scientists observe the environments that surround them by dividing the light they emit in several wavelengths. This process, called spectroscopy, allows them to determine the characteristics of celestial objects.
To find black holes, scientists are looking for gas around them. The light of the gas moving away from us is stretched in wavelengths which are redest, while the light of the gas moving towards us is compressed in wavelengths which are more blue.
In this way, the research team involved in the new study managed to distinguish the spectroscopic signature from the black hole of Capers-LRD-Z9.

Local small red dots
By examining more closely the Capers-LRD-Z9, the researchers realized that it belonged to a class of galaxies called “Little Red Dots”, discovered for the first time by the JWST in 2024. These galaxies appear only during the 1.5 billion years of the universe, and their brightness and their compact have perplexed for 1.5 billion years.
“The discovery of small red dots was a major surprise of the first JWST data, because they did not look like galaxies seen with the Hubble space telescope,” said co-author Steven Finkelstein, director of the Cosmic Frontier Center based at the University of Texas in Austin, in a press release. “Now we are understanding what they have and how they have become.”
Capers-LRD-Z9 and its black hole could have answers to scientists, who suspected that the supermassive black holes cause the brightness from the small red dots. The brightness in a galaxy normally comes from a large number of stars, but small red dots were formed when large stars were not yet ridiculed through the universe.
Despite their representation as dark and devouring voids, black holes actually produce a brightly brightness of light. However, it is not the black hole itself that shines – they are invisible and cannot emit or reflect the light; Instead, it is the gas material that flows around a black hole that generates light when heated and compressed.
The researchers confirmed that this phenomenon occurred in Capers-LRD-Z9 following its black hole.
Rethink the evolution of black holes
Capers-LRD-Z9 is not simply surprisingly shiny, but it also has a separate red color, like all the other small red dots. The researchers believe that this redness is the result of the gas surrounding the black hole, which can register in light in red wavelengths.
The size of the black hole in the galaxy is also a striking feature, as it is estimated at 300 times larger than our sun. Unlike black holes formed later in the history of the universe, those born in the first hundreds of years would not have had access to so many resources to put on.
“This adds growing evidence that the first black holes have become much faster than possible,” said Finkelstein. “Or they started much more massive than our models predict it.”
The researchers hope to collect additional data on the new galaxy and its black hole, which could lead to an improved understanding of the evolution of black holes in the first days of the universe.
