In a groundbreaking discovery, astronomers have identified a binary star system orbiting perilously close to a supermassive black hole, a phenomenon never before observed. The findings, published in Nature Communications on December 17, 2024, challenge our understanding of stellar dynamics in extreme environments.
The research, led by Czech astronomers Michal Zajaček and Vladimír Karas, sheds light on how binary stars—pairs of stars orbiting each other—can survive in the intense gravitational fields near supermassive black holes. These cosmic “monsters,” found at the center of nearly every large galaxy,are known for their ability to destabilize and tear apart star systems.
A Rare Cosmic Dance
supermassive black holes,like Sagittarius A (Sgr A) at the heart of our Milky way,are colossal structures with masses millions of times greater than the Sun.While stars can form and orbit near these black holes, binary stars have never been observed surviving in such close proximity—until now.
The binary system, designated D9, is located approximately 2.7 million light-years from Earth. ItS stars, with masses 2.80 and 0.73 times that of the Sun, orbit each other every 372 days. “This system is relatively young, and its components are at an ideal distance from each other,” explains astrophysicist Anna Ciurlová from the University of California, Los Angeles. “If thay were too far apart, the black hole’s tidal forces would pull them apart.If they were too close, they might merge into a single star.”
The Fragile Balance of Survival
The discovery raises intriguing questions about the stability of binary systems in such extreme environments.While the stars in D9 currently maintain a delicate balance, their future remains uncertain. “A number of questions surrounding these objects still remain open,” Ciurlová adds.
The table below summarizes key details about the binary star system and its environment:

In a groundbreaking discovery, astronomers have identified a binary star system, named D9, orbiting perilously close to Sagittarius A, the supermassive black hole at the center of our galaxy. This marks the first time a stellar pair has been detected in such an extreme environment, challenging long-held assumptions about the destructive nature of black holes.
The discovery was made using data from the European Southern Observatory’s very Large Telescope (VLT) in Chile, a facility supported by the Czech Republic, among other nations. ”We actually got lucky with this binary,” said led author Florian Peissker of the University of Cologne. “We observed the system at just the right moment.”
The D9 system, located in the dense S cluster surrounding Sagittarius A, is estimated to be just 2.7 million years old—a cosmic infant by stellar standards. Though, its fate is already sealed. The intense gravitational forces between the two stars are expected to cause them to merge into a single, larger star within the next million years.This discovery not only sheds light on the resilience of binary stars but also challenges the notion that black holes are purely destructive forces. “It helped us understand how stars can survive in an environment with extreme gravity, and it could pave the way to detect planets near Sagittarius A. Black holes are not as destructive as we thought,” Peissker explained.
The presence of gas and dust around the D9 system further suggests it is indeed a very young star system. Co-author Michal zajaček from Masaryk University and the University of Cologne noted, “The D9 system shows clear signs of the presence of gas and dust around the stars, which indicates that it might very well be a very young star system.”
This finding also overturns previous beliefs that the extreme conditions near supermassive black holes prevent star formation. The discovery of young stars and now a binary system in the vicinity of Sagittarius A proves that stellar birth and survival are possible even in such unfriendly environments.
Key Insights About the D9 Binary Star System

The discovery of D9 opens new avenues for understanding the dynamics of star formation and survival in extreme environments. It also raises intriguing questions about the potential for planets to exist near supermassive black holes, a possibility that was once thought to be unachievable.
As astronomers continue to study the D9 system, they hope to uncover more secrets about the interplay between stars and black holes.This discovery not only enriches our understanding of the cosmos but also reminds us of the universe’s capacity to surprise and inspire.

Mysterious G Objects Near Sagittarius A: A Gateway to Discovering Planets in the Galactic Center?
The enigmatic region surrounding the supermassive black hole Sagittarius A at the heart of our Milky Way galaxy continues to baffle astronomers. Among the most intriguing objects in this cluster are the G objects,which behave like stars but resemble clouds of gas and dust. Recent observations have shed new light on these mysterious entities, revealing clues about their nature and even hinting at the possibility of planets forming in this extreme environment.
The Discovery of Binary Stars in the S Cluster
During observations of the G objects, researchers identified a surprising pattern in the object labeled D9.Spectroscopic data revealed repeated changes in the radial velocity of D9, suggesting it is not a single star but a binary system—two stars orbiting each other. This discovery marks the first confirmed binary star system in the S cluster, a group of stars orbiting perilously close to Sagittarius A.
“I thought my analysis was wrong,” admitted Dr. Peissker, a key member of the research team. “But the spectroscopic pattern in question lasted for about 15 years, and it was clear that this was indeed the first binary observed in the S cluster.”
What Are G Objects?
The findings provide new insights into the nature of G objects. Researchers now believe these mysterious entities could be a combination of binary stars that have not yet merged and leftover material from already merged stars. This dual nature explains why G objects exhibit both stellar and gaseous characteristics.The exact origins of these objects, and also how they formed so close to the supermassive black hole, remain a mystery. Though,advancements in astronomical technology are poised to unlock these secrets.
Cutting-Edge Tools to Unravel the Mysteries
The Very Large Telescope (VLT) in Chile, equipped with an upgraded interferometer, and the METIS instrument on the upcoming Extremely Large Telescope (ELT) are set to revolutionize our understanding of the galactic center. These instruments will enable astronomers to make more detailed observations of Sagittarius A and its surroundings, revealing the true nature of known objects and uncovering new binary systems and young stars.
“Our discovery will later make it possible to think about the presence of planets in this area, as they generally frequently enough form around young stars.It therefore seems likely that the detection of planets in the center of the Galaxy is only a matter of time,” concludes Peissker.
The Potential for Planets Near Sagittarius A
The discovery of binary stars in the S cluster opens the door to the possibility of planets forming in the galactic center. planets typically form in the protoplanetary disks around young stars, and the presence of young stars near Sagittarius A suggests that planets could exist in this extreme environment. Detecting these planets, however, will require even more advanced observational tools and techniques.

At the center of our galaxy, the Milky Way, lies a cosmic enigma: Sagittarius A (abbreviated Sgr A), a supermassive black hole approximately 26,000 light-years from Earth. Located in the constellation Sagittarius, this colossal entity weighs an astounding 4.3 million times the mass of the Sun. despite its immense size, Sgr A is relatively inactive, earning it the nickname of a “starving” black hole.
The Discovery of Sagittarius A
Sgr A was first identified in 1974 as a source of radio radiation. However, its confirmation as a supermassive black hole came much later, through observations of fast-moving stars orbiting close to it. These stars, whizzing around the black hole at incredible speeds, provided the first concrete evidence of its existence.
In 2022, a groundbreaking achievement in astrophysics was made when the Event Horizon Telescope (EHT) captured the first image of Sgr A. this historic image revealed the black hole’s shadow and the radiation emitted by the material swirling around it. The EHT, a global network of telescopes, achieved this feat by combining data from multiple observatories, effectively creating a virtual telescope the size of Earth.
Key Features of Sagittarius A
Sgr A is surrounded by a dense disk of gas, dust, and stars. While it does not emit light itself, its presence is detected through its gravitational effects on nearby objects and the high-energy radiation released when matter falls into it. Compared to other supermassive black holes, Sgr A is relatively quiet, absorbing only small amounts of matter and emitting minimal radiation.
Why sagittarius A Matters
Understanding Sgr A provides critical insights into the behavior of supermassive black holes and their role in shaping galaxies. its relatively inactive state offers a unique prospect to study these cosmic giants without the interference of intense radiation or violent activity.
