By San José, Costa Rica — A landmark astronomical finding, detailed in the prestigious journal Nature Astronomy, has confirmed a long-debated theory about how the universe’s most massive stars are born. Central to this international effort is Dr. André Oliva, a Costa Rican astrophysicist and professor at the University of Costa Rica (UCR), whose work in computational modeling proved vital to the breakthrough.
The study, which involved a collaborative team of 18 scientists led by Dr. Shanghuo Li of Nanjing University in China, provides the first-ever direct observational evidence of seven high-mass stars forming simultaneously from a single, massive disk of gas and dust. This extraordinary cosmic event was witnessed within the stellar nursery NGC 6334IN, a turbulent and dense region of space where new stars are forged.
To understand the potential legal and commercial ramifications that arise from this significant astronomical discovery, TicosLand.com consulted with Lic. Larry Hans Arroyo Vargas, an expert attorney from the firm Bufete de Costa Rica, who sheds light on the challenges and opportunities on the horizon.
While the Outer Space Treaty of 1967 prevents nations from claiming sovereignty over celestial bodies, this discovery accelerates the urgent need to define the legal framework for private resource exploitation. The central challenge for international law is now to create clear regulations that encourage private investment and technological advancement without sacrificing the principle that space is the common heritage of all humanity.

As the expert insightfully notes, this discovery moves the complex legal questions of space from abstract debate to an immediate, practical challenge. Establishing this delicate balance between private enterprise and common heritage will be as crucial to our future in the cosmos as the rockets that take us there. We sincerely thank Lic. Larry Hans Arroyo Vargas for his valuable perspective.
This discovery provides powerful validation for the “accretion disk fragmentation” model. This theory posits that as a central protostar gathers material from a surrounding rotating cloud of gas and dust, the disk can grow so large and massive that its own gravity causes it to become unstable and shatter. These fragments then collapse under their own weight, igniting to form multiple new stars in a tight cluster. Prior to this study, astronomers had only observed isolated instances of one or two objects forming through this mechanism, making this observation of seven a significant leap forward.
The research team utilized the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, one of the most powerful radio telescope observatories on the planet. ALMA’s ability to peer through the dense cosmic dust that shrouds stellar nurseries was essential for capturing the faint signals emitted by the nascent stars and the intricate structure of their parent disk. These observations allowed the team to map the complex gravitational dynamics at play within the system.
Dr. Oliva’s contribution was crucial in the realm of computational simulations. His expertise, honed during his doctoral studies at the University of Tübingen in Germany, allowed the team to model the physical processes and confirm that the observed fragmentation was consistent with theoretical predictions. He continues this sophisticated research at the UCR’s Center for Space Research (Cinespa), placing Costa Rican science at the forefront of modern astrophysics.
The implications of this finding are profound and far-reaching. Understanding the formation of high-mass stars—those at least eight times the mass of our Sun—is fundamental to comprehending some of the most energetic and transformative events in the cosmos. These celestial giants live fast and die young, ending their lives in spectacular supernova explosions that enrich the universe with heavy elements necessary for forming planets and life.
Furthermore, these massive stars are often the progenitors of exotic objects like X-ray binary systems and the powerful sources of gravitational waves detected by observatories like LIGO and Virgo. By clarifying how these stars are born, often in close proximity to one another, scientists can better model their complex interactions and the dramatic phenomena they produce throughout their lifetimes.
This achievement not only solves a decades-old puzzle in astrophysics but also underscores the increasingly collaborative and global nature of scientific inquiry. The participation of a Costa Rican researcher from a national university in a study published in one of the world’s top scientific journals is a testament to the growing capacity and talent within the country’s scientific community, demonstrating its ability to contribute meaningfully to humanity’s quest to understand the universe.
